M16 page talk

This talk did not have a header and was from discussion in March 2005

I think M16 rifle or even M16A1 rifle is a better name. There are too many "M" terms used in the US military, like M151. Would you know that was a jeep, if I hadn't just told you? --Ed Poor

I knew M151 was a jeep. -Weps

M16 rifle's reasonable; the M16A1 doesn't exist in wide use anymore. The US Army uses the M16A2, which cannot be fitted with attachments; the M16A4 can(the Marines are the biggest useres of this system). The US also uses the M16A3 which is a full auto version of the M16A2. However, the latter is not in wide use either; therefore, the Army has switched to the M4 series. In short, it's either M16 rifle, M16 (rifle), Colt M16, or M16A2 rifle (I personally like M16 rifle or Colt M16). 21:46, 25 Mar 2004 (UTC)

Actually the M16A2 can use the M203 and LSS.


I'm in favor of M16 rifle. There's no sense referring to a specific AX variant, and Colt has no particular claim to the design other than being the initial manufacturer. Armalite produced the initial design, and it's currently manufactured for the US by FNMI.

--Mmx1 01:02, 29 July 2005 (UTC)

Actually Colt, Armalite, FN, Panther DPMS,and Bushmaster make the M16. Colt and Bushmaster make US Military issue M16's.

Armalite, Panther Arms/DPMS, and Bushmaster make M16 pattern firearms, not M16s. Colt and FN make the M16s in use by the US military, Bushmaster made a number of contract M4s under contract in the early '90s. --Thatguy96 10:33, 2 Jan 2006

The M16A1 is nolonger used (Except by Nat Guard units), the M16A2 is standrad issue for rear enchlon units, the M16A3 is used by foward support units, and he M4 and M4A1 are used by front line units. The Marines use the M16A4 and M16A2. The M16A3 is a Auto version and the M16A4 is a RIS version.


The M16 and M16A1 are both still in USAF inventory, despite their best efforts to completely strike it from their arsenals. The M16A2 is still standard issue for frontline USAF security units and some Marine Corp units, along with US Army Reserve. M16A3 was purchased in small numbers by the USN for the SEALs and may or may not have filtered down to other units. The M4/A1 is used by various front line units. The M16A3 is NOT equiped with a flattop or M5 RAS as standard, and the M16A4 in only certain cases has the M5 RAS as standard. --Thatguy96 10:36, 2 Jan 2006

According to it "entered Army service in 1964". Anyone know how this relates to the "service history" box where it says "1960 - present"? Thewonky

The USAF acted first when it procured 8,500 rifles in 1961. -- Thatguy96 19:01, 24 May 2007 (UTC)

M-16 or M16?

discussion about dash in June 2005

Which is it? 03:21, 11 Jun 2005 (UTC)

-- There is no dash in the designation M16 in official documentation or in the markings stamped on the side of military rifles. D.E. Watters 04:32, Jun 11, 2005 (UTC)

Why has this page not been moved to M16 (rifle) then? I'd do it myself, but I don't know much about gun designations and so maybe there's more to it than what I know. ✈ James C. 22:31, 2005 Jun 11 (UTC)
--This page actually started as M16 (rifle). On May 30, 2005, someone moved it (and the Talk page) to M-16 (rifle). I'd move it back myself, but I don't know how. --D.E. Watters 01:01, Jun 12, 2005 (UTC)
I moved the article back - for future reference, you can just click the "move" button in the bar atop the articlespace. --FCYTravis 06:48, 13 Jun 2005 (UTC)
I guess that was too obvious! Thanks for the info. --D.E. Watters 07:23, Jun 13, 2005 (UTC)

If there was M16/203 already, than why we need M16, it's mainly the same? Only because of HE grenade? —The preceding unsigned comment was added by (talkcontribs) 13:12, February 18, 2007 (UTC)

I think CAR15 is better than M16. —The preceding unsigned comment was added by (talkcontribs) 13:23, February 24, 2007 (UTC)


This article's 2nd paragraph is unnessesarily widened and hovering over the main picture in my browser (Safari 1.0).

- drakonok at yahoo dot com

That happens with various browsers (I think those that use the Gecko engine, namely Mozilla, Mozilla Firefox, Konqueror, and Safari) for no reason. Try refreshing. 21:46, 25 Mar 2004 (UTC)
Konqueror and Safari use KHTML, not Gecko. In Konqueror I find that mouseovering the article/disussion/et cetera tabs at the top of the page fixes its width.

The M203 grenade launcher is probably an important enough accessory to merit some text and a link for this article.

Added internal link to M203. Tronno 18:07, 2 Oct 2004 (UTC)

I'm not too keen on the "this is how you should shoot it" section. At the very least it needs a "don't kill yourself" thing. But this means giving Normal Safety Procedures (as they are known in Britain).

What's the source on China being a manufacturer of M16s? I'm aware that Norinco (state arms company) manufactures AR15s for export civilian sales, and that Taiwan (not China) manufactures an M16 clone, but the end statement including China as a major manufacturer is not really correct.

If I remember correctly, that information is available on the Colt website. Maclyn611 16:37, 24 May 2004 (UTC)

In the section "Conarc", para 2, last sentence, it states: "Winchester entered a design based on their M1 Carbine and even Earle Harvey of Springfield attemptd to before his bosses refuse to consider such a design while work on the T44 continued".

Can anyone make sense of this ?

I don't know if it's a good idea to imply that women are weak and need lower recoil rifles than men. I know some who have no problems firing a .303. Nvinen 13:48, 12 Feb 2005 (UTC)

Leftovers from assault rifle

Feel free to merge etc:

It soon became clear to the US that the British had been correct all along, and the M14 proved incapable of being fired accurately in fully-automatic mode due to heavy recoil and muzzle climb. This meant the US had spent a lot of time and money changing from one semi-auto system, the Garand, to another, the M14. Other forces found themselves with the same problem, leaving NATO with semi-auto weapons facing true assault rifles, notably the famed AK-47, being built by the Soviets and deployed world-wide.

Into the story comes Eugene Stoner and the CONARC project to develop a new light-weight weapon for US use. His design combined the EM-2's carrying handle, the StG44's ejector port cover and hinged design, a gas-operated firing mechanism from a Swedish rifle, and a an inline stock for better control in automatic. Unlike most designs, where the stock is bent down from the barrel to raise the sights up to eye level, the new design had a raised sighting system. The result was the AR-15, firing a .223 inch (5.56 mm) round, which handily beat the other designs tested by CONARC. After special forces used it in Vietnam and worked out some early deficiencies, the new M16 rifle became the standard US weapon.

Dan100 12:16, Feb 20, 2005 (UTC)

regarding the sentence in CONARC :""Winchester entered a design based on their M1 Carbine and even Earle Harvey of Springfield attemptd to before his bosses refuse to consider such a design while work on the T44 continued"."

I believe it's an enumeration of other designs submitted for the CONARC competition. Winchester with a M1 variant. Earle Harvey would have entered a design but his superiors refused to divert work from the T44.

Edited to reflect these changes.

--Mmx1 01:20, 15 May 2005 (UTC)


It is so bloody annoying the way the US military has a jillion different names for things.

I mean, I thought that the AR15 was the original Stoner-designed pre-military-adoption version, which apparently it is, but it was also the different-in-appearance-with-some-features-added military version (also known as the M16E1), AND it's also the modern semi-only civilian version, which has various different appearances.

I mean, what the hell is that? The US military gives something a "test name" like the XM-numberal here, then when it's adopted gives it an M-designation name, usually with a different number. Then of course is the fact that the M-whatever will usually also be the name of a tank, a rocket launcher, and a fuggin' can opener.

For instance: There's an M1 rifle, an M1 carbine, an M1 submachine gun, and I think there's also an M1 grenade IIRC.

So I might have made some errors correcting what I thought were errors. Or everybody could have been wrong.

Why can't the US armed forces just call assault rifles AR-year of adoption, pistols P-year of adoption, etc? By this the M-16A1 would be the AR67.

They had, until WW2 for the most part, used an M+year adopted (like in M1911A1), but the system was changed to be sequential based on the type of equipment. Like Rifle, M1 or Carbine, M1 or Carbine, M2. The big problem with your idea, and what was going on in the early years of WW2 ws the adoption of multiple types of equipment and multiple variations rapidly. For example, the M3 Grant and M4 Sherman tanks were adopted in a very short order, along with a light tank or two. How confusing would it be to be the commander of a Tank Battalion with T1942's and LT1942's after upgrading from T1940's and LT1941's while your rifles are R1936A2's and... You can see how quickly and annoying all the numbers get. *smirk* Deathbunny 06:40, 17 June 2006 (UTC)

It worked fine for the Germans, then after WWII the Germans started randomly affixing numbers to things too. I mean, I can tell when an MP40 was introduced: 1940. Is a G36 supposed to have been introduced in 1936? No, but neither was it introduced in 2036.

Just noticed this. G36 isn't arbitrary. The Germans follow a system akin to the US System where the number is sequential based on type. Gewehr 36 is the 36th rifle adopted by the Germans since the end of the war. Since the German term Gewehr covers rifles and carbines or all types, you see lots of things with a G designator, but if I had my copy of Ed Ezell's Small Arms Today I'd list Gewehr's 1-35 for you so you could see. The ones I have on hand are:
  • G1: 7.62x51mm NATO FN FAL 50.00 battle rifle variant
  • G2: 7.62x51mm NATO Sig 510-4 battle rifle
  • G3: 7.62x51mm NATO HK G3 battle rifle
  • G4: 7.62x51mm NATO Armalite AR-10 battle rifle
  • G5: 7.62x51mm NATO Steyr SSG-69 bolt-action rifle
  • G8: 7.62x51mm NATO HK 21 machine gun variant; aka “HK 81”; short barrel
  • G11: 4.73x33mm HK G11 assault rifle
  • G21: 7.62x51mm NATO AI AW bolt-action rifle
  • G22: .300 WinMag AI AWM-F bolt-action rifle variant
  • G23: .300 WinMag AI AWM bolt-action rifle
  • G24: 12.7x99mm AI AW50F bolt-action rifle
  • G36: 5.56x45mm NATO HK G36 assault rifle
  • G37: 5.56x45mm NATO Sig SG551 SWAT carbine

In fact, the only arbitrary one I'm familiar with in the system is the G82 designation for the Barrett M82 AMR. -- Thatguy96 17 June 2006, 10:49

GAH! And now looking it up, it seems that the M16E1 was also called the M16A1. But then again I have seen in reputable sources the M16E1 DIFFERENTIATED from the M16A1. My head hurts.

M-16 -- Had Y charging handle, sloped bolt catch, 3 prong flash hider, green fiberglass buttstock and handguards. M-16E1 T charging handle, bird cage flash hider, studded bolt catch, black buttstock and hand guards. US Air Force received 1,900 or 19,000 M-16's in the original order, follow on orders were the M-16E1. I was a US Air Force Redhat (Combat Arms Instructor '83-90) we had serial numbers below 5000 on 2 rifles and which were all marked as Armalite Colt AR-15 models. US Army used ball propellant which left alot of residue and required the bolt assist which they put on the M-16A1 and I believe the A2 added sights and the ejection bump behind the ejection port.

I just found out at that the Air Force M-16 was different from the US Army M16E1. --Edward Wakelin

-- The XM16E1 became the M16A1. Certain improvements like hard-chromed chambers and bores did not occur until after its adoption as the M16A1. --D.E. Watters 04:32, Jun 11, 2005 (UTC)

How are we sure that the M16A3 had the A2 style style carrying handle. Both globalsecurity and world guns has it having an RIS.

100% sure because this is what the most recent US Army Technical Manual says. thatguy96 09:55, Nov 18, 2005 (UTC)
A RIS can be fitted to any AR-15/M16-type upper that has barrel contours not exceeding those of the M16A2 plan and whose barrel is attached in the same manner. Theoretically, you could put a RIS on an M16, M16A1, M16A2, etc. What doesn't work is certain other types of RIS, like the Swan Sleeve, that has a piece that connects the RIS to the upper rail of a flat top upper. You also have difficulties being able to mount optics on an RIS because of the carrying handle on the A1/A2 being in the way and/or pushing the optic further forward than optimum for eye relief. (You can use a riser on the optid to clear the handle.) Deathbunny 06:40, 17 June 2006 (UTC)

M16 variants

This is what I believe to be correct, anybody who sees mistakes please notify me.

AR-15: Eugene Stoner's trial version, also the name for the civilian version of the various M16 models. M-16: USAF version, basically the AR-15 with a ejection port cover. M-16E1: US Army version, USAF version plus forward assist. M-16A1: Above, with improved flash hider, chromed insides. M-16A2: Above, with redesigned furniture, 1:7 twist heavier barrel, semi/3rb firing modes, improved rear sight/carry handle. M-16A3: Above, with flat-top Picatinny rail instead of carrying handle. M-16A4: I have heard this term used... Supposedly it's an M16A3 with full-auto capability? --Edward Wakelin

-- The ejection port cover was standard from the very beginning with the AR-10 and AR-15. There were a series of internal changes with the introduction of the USAF M16. The Army rifles were referenced as XM16E1 until its offical standardization as the M16A1. The M16A3 is the full-auto version of the M16A2 and retains the carrying handle. The M16A4 is the flat-top version of the M16A2. --D.E. Watters 04:32, Jun 11, 2005 (UTC)
M-16A3: Above, with flat-top Picatinny rail instead of carrying handle, fully automatic.
M-16A4 (M-16A2E4 MWS): Above, with single, and burst fire only. It is fitted with Full length Knights Armament M5 RAS (Rail attachment system)RIS. The M-16A2E4 MWS (Modular Weapon System) is currently the USMC issue weapon instead of the m4 carbine series, It was chosen after competing in multiple military trials. It is the primary weapon currently being used in Iraq by the Marine Corps. --
-- US Army Technical Manuals clearly show the M16A3 as having a carrying handle. The latest versions of the same manuals clearly show that the flat-top variant of the M16A2 is the M16A4. We have addressed the differences between the military and civilian designations elsewhere in the article. In addition, the M16A2E4 designation has long since been replaced by the designation M16A4. --D.E. Watters 15:34, 19 September 2005 (UTC)

But, confusingly enough, the XM16E1 was different from the M16A1, and also different from the USAF M16...

Honestly, gun nomenclature is just messed up. It's like they roll a friggin' die. "OH WOW, OUR NEW TANK WILL BE THE M2D6+4" "OLOL YOU KILLED MY ORC". --Edward Wakelin 13:52, 11 Jun 2005 (UTC)

-- Yes, a XM16E1 of 1965 production is different from a M16A1 in 1971. However, the differences we associate with the M16A1 were either already being introduced for the XM16E1 late in its production (birdcage flash hider and heavy buffer) or months and years after the M16A1's standardization (hard-chromed chambers and bores). There was no effective difference between the last XM16E1 produced and the first M16A1 produced. The difference was merely a change of designations due to its offical change in status from Experimental to Standard A. --D.E. Watters 18:49, Jun 11, 2005 (UTC)

I've always thought the M16A1 was the one that by 1968 or 69 or so most troops were using... Or was that the M16E1A1? XM16E1A1?

And how was the M16E1 experimental, if eventually the vast majority of troops in Vietnam were using it? --Edward Wakelin

-- The original XM16E1 and M16A1 were upgraded to then current production standards as the parts supply allowed. Effectively, all of the Army's AR-15-type rifles in 1969 were becoming M16A1 whether through initial production or armorer upgrades. Just remember that barrels with fully chromed bores were not available for production rifles until 1971.
The XM16E1 was considered experimental primarily because the Army's first purchase was supposed to be its only purchase. Originally, it was only meant to cover the Army's rifle shortfalls for the end of M14 production to the first issue of the SPIW. The delays in SPIW's development and increased demand for the XM16E1 from US troops in South Vietnam gave the US Army brass a reality check. The XM16E1 was declared 'Standard A' (becoming the M16A1) primarily because was already becoming a de facto standard. --D.E. Watters 01:01, Jun 12, 2005 (UTC)

AR15 USAF, Standard model.

M16: US Army Designation, same as the AR-15 different designation. --

Wrong. This is a US Air Force designation as well.--Asams10 04:27, 3 January 2006 (UTC)

M16A1: Reconfigured M16. Foward assist, three round burst, slowed ROF. --

WRONG. The M16A1 is simply the M16 with a Forward assist and notched. Later, M16's all got notched bolt carriers. It most certainly does NOT havea 3-round burst.--Asams10 04:27, 3 January 2006 (UTC)

M16A2: Reconfigured and retooled. New sights, new heat sheild, new pistol grip. --

AND new handguards, new stock (longer and stronger) New flash supproesor and DOZENS of other changes.--Asams10 04:27, 3 January 2006 (UTC)

M16A3: RIS version of the M16A2

M16A4: Automatic RIS version of the M16A2 --

  • Incorrect yet again. The M16A3 is the full-auto variant of the M16A2, while the M16A4 is the flattop version of the M16A2. --D.E. Watters 14:36, 3 January 2006 (UTC)

CAR15: Shortened version of AR-15/M16

M4: Shortened M16A2

M4A1: RIS version or M4

XM117: M4 with an enlongated flash surpressor.

M733 Commando: Super short M4 --

These are wrong, refer to the table in the main article for accurate descriptions of the models. Refer to the Colt Commando and M4 pages for accurate info on the "CAR15", M4, M4A1, and XM177, as well as, the Colt Model 733. --Thatguy96 10:33, 2 Jan 2006

--There seems to be confusion about the M16A2, A3, and A4 models. The M16A3 is not a full-auto version of the A2: the A2 is a burst version of the A1. The A3 is the full-automatic version of the burst-capable M16A4, both of which have a flattop receiver.

Unfortunately, there is no confusion. You are confused. You can easily find a copy of US Army Technical Manual (TM) 9-1005-319-23&P which clearly supports the reality that the M16A3 is identical to the M16A2 (with a fixed carry handle), except in the fire control group. The M16A2 is also not a burst capable version of the M16A1, but a version with a variety of improvements and changes (not all cosmetic) over the A1, that also happens to have the 3-round limiter. -- Thatguy96 23:16, 29 March 2007 (UTC)

--Odd, since every resource I've read has stated that the M16A3 has a flattop receiver (and shows pictures of such).

What's "every resource," because the US government, Colt, Duncan Long, Chris Bartocci, and Daniel Watters all agree with what I've presented. -- Thatguy96 06:40, 30 March 2007 (UTC)

You'd think

That military nomenclature, for whatever, would be one of the places where simplicity and good organisation would be needed, to save lives.

But no, they have to make everything SO DAMN CONFUSING.

Heh heh, ask anyone in the military - that's SOP for us. I'd like to think it's to make our minds sharper by keeping us from using shortcuts or 'the easy way' but in all honesty it's probably because no one really thought it through. 11:03, 21 February 2007 (UTC)


When was it actually being used by the Army? Didn't the USMC adopt it slightly earlier? Or later? I remember reading earlier, but later would make more sense, given that the Corps usually gets the new stuff last...

-- The USMC did indeed adopt the M16A2 first. They placed their first order in November 1983. The US Army was holding out for something better, and did not place their first major order until March 1986. --D.E. Watters 00:24, Jun 12, 2005 (UTC)

-- I have no idea what I'm doing here, I'm a complete newbie here; so if I goof up, someone please erase whatever I may have done wrong.

My comment regarding the M16A+ is in reference to one sentence that, in the context of making the M16A2 a three-round burst, was something like "poorly trained soldiers would 'spray' on fully auto, wasting ammunition..." (not verbatim, it took me ten minutes to get to this point.) While not entirely inaccurate, it doesn't fully explain the circumstances of the situation.

The term we used was "spray and pray." And certainly, most of us were very inexperienced, but not necessarily poorly trained; and all of us were terrified. But to put it into the proper perspective, it would more properly be termed as "supressive fire." Try to imagine a city or farm kid from the USA who has never seen a jungle, fighting against an enemy to whom this is native turf. They were invisible, for the most part. Now, for a grunt unit taking fire without a visible enemy, the only option until you could call in air or artillery support was to "spray and pray" - fire on "rock and roll" in their general direction and hope you either hit someone, or at least keep them occupied enough so they couldn't get a bead on you or your buddies. Selective fire requires a target; but the M16A1 fired on full auto by a couple of dozen people can throw thousands of rounds in the general direction of the bad guys in mere seconds and probably kill a few by sheer luck.

I don't recall the exact numbers of rounds expended to enemy KIA ratio, but it took a lot of bullets per kill. It wouldn't be accurate anyway, because the enemy KIA ratio was never accurate.

In Iraq or Afghanistan (never been there) I would imagine a three round burst would be more appropriate because you would probably have a target before you squeezed off.

I'm just not comfortable with the wording of that sentence because it doesn't convey the reality of the situation. Literally, it is factual; however I think a tiny bit of editing to be in order. I'm not about to try this until I learn far more about this system than I have learned in just a few weeks.

VFW Loki 14:03, 16 February 2006 (UTC)

yea i was wacting the military channel about the m16 and it said in 1 study it took 500000 bullets from 1 m16 to kill one vietkong. or something rediculas lkike that.

M16 performance and quality

It's probably PoV, but should there be any mention of the performance and quality of various M16 models?

There is quite a bit of criticism of the M16A2 out there, eg: There are better weapons firing the same ammo (The C7 series, a development of either the M16A1 or A2, is generally considered to be higher quality, the G36 is considered to be top-notch especially with the 2-scope layout, the FAMAS G2 is supposed to be excellent, etc etc etc).

The weapons created for the ACR competition or whatever it was called were all generally better, but they didn't reach the unrealistic 100% effectiveness bar.

--Edward Wakelin 17:56, 12 Jun 2005 (UTC)

There is also considerable difference of opinion about the ammunition itself, and some slightly inaccurate information in the main page. If you run real M855 Ball through a real 20" barreled AR or M16A2, most production lots originating in the US are going to clock in at around 3050 ft/sec muzzle velocity. Compare and contrast the real-world 3250-3300 ft/sec of M193 Ball from the same weapons. Note that some M855 / SS109 is considerably warmer than this. Some production runs of IMI (Israeli) M855 approach 3150 ft/sec from the muzzle of a 20" rifle, for instance. If M855 is only doing 2900 ft/sec out of an M16A2 (not an M4 or M177, an M16A2 with a 20" barrel) then something is definitely wrong with that production lot and it is far outside acceptable specs.
There is no practical difference in trajectory between the two. Even an optical sight using a bullet drop compensating reticle or a bullet drop compensating elevation turret zeroed for one will be within one minute of arc of the other's trajectory (once it is re-zeroed at 100m or 200m with the other ammunition) out past 600 meters--which is a lot further than the usual range of engagement with an assault rifle on the modern battlefield.
To the extent that there is any difference in trajectory at all, the M16A2/M855 combination is considered to have slightly greater effective range than M16A1/M193, the reverse of what the article states. The M16A1 with M193 is normally zeroed at 250m, while the M16A2 with M855 is zeroed at 300m, at least in USMC service. All else being equal, M855, despite its slightly lower initial velocity, shoots ever so slightly flatter than M193 due to the longer, heavier bullet retaining velocity better, ballistic coefficient approximately 0.310 versus approximately 0.240. This is the reverse of what the article states.
M855 and M193 have their strengths and weaknesses. M855 is much more expensive to manufacture, but retains velocity somewhat better downrange and under most circumstances has slightly superior performance against hard barriers due to the steel insert in the point of the projectile. M193 is considerably less expensive and may be more accurate at long range due to the complex construction of the SS109 type projectile (if that steel insert is an imperceptible bit off-center inside the bullet, accuracy past 200m or so will suffer very badly). M193 seems to be slightly more destructive in soft tissue than M855, at least out to 150m or thereabouts, though the reasons for this are not conclusively known (speculation centers on slightly higher velocity at impact and the lack of an steel insert making the projectile's point prone to bending to one side on impact, initiating yaw sooner and more reliably). M193 Ball seems to penetrate slightly thicker sheet steel than M855 out to 50m or so, again perhaps due to higher velocity, though the difference is slight and varies from production lot to production lot.

If we had any hard facts, sure. I've fired the FAMAS and thought it was horrible in every way. I use the C7 all the time and while I think it is an excellent rifle, I suspect the supposed superiority is just "made in Canada" propaganda. I have heard that US Army ammunition is of lower quality than what Canadians use, which may be an alternate cause of performance problems. There is so much speculation. Without hard facts (quantitative data) I think we should avoid wading into performance debates. --M4-10 20:36, 12 Jun 2005 (UTC)

OT, what was the FAMAS like? Bullpup designs in general are definitely shorter, but I've heard bad things about the reloading movements being awkward, bullpup designs being awkward to fire from a prone position, etc.

PS: Are you employed in one of the militaries that uses the C7, or what?

--Edward Wakelin 23:24, 12 Jun 2005 (UTC)

I found the FAMAS to be off-balanced and the movements were awkward. I initially conceded that I may be prejudiced against bullpups due to inexperience but that same day I handled and fired the Steyr Aug and loved it. The FAMAS safety is in the trigger guard which is dumb and the cocking mechanism is like the AR-10 (mounted on top of the weapon below the sight rail) which I didn't like much either. The only thing I liked about the FAMAS was the built-in foldable bipod.

I am Canadian military, reserve infantry officer. --M4-10 02:42, 13 Jun 2005 (UTC)

I've heard the AUG has problems with the safety... Or is that just the Australian version? I've heard bad things about the Australian version. The FAMAS trigger-safety setup does look rather unsafe, and the cocking mechanism looks like it would involve a bit more movement that should be necessary.

I'm thinking of joining the regular Forces or the reserves when I'm out of university, if I'm eligable and the Forces haven't collapsed funding- or morale-wise. --Edward Wakelin 13:28, 13 Jun 2005 (UTC)

I've only fired U.S. Army weapons so I can't comment on comparisons between them and others, but I can say with absolute confidence that the M16A2 does leave a lot to be desired.. the biggest issue with the M16A2 is jamming, usually from double-feeds (when two bullets get stuck in the chamber while loading.. because they're copper-jacketed and copper is a soft metal, the 15-pounds of force from the bolt slamming into it tends to fix them in place and you often need to break out a Gerber to dislodge the rounds, which itself can be dangerous if the weapon is hot due to cookoffs). Weapon malfunctions occur either because the weapon is old and worn down (often) or because sand, dirt or other foreign material got into the chamber and interfered with the bolt or magazine. I know that when I go to the range to qualify on the M16A2 I have to clean the weapon for one or two days beforehand otherwise it WILL malfunction (reliably) and when we come back from the range we have to clean them for a good one to two hours.. The amount of carbon that builds up on the firing pin and in the chamber interferes quickly with normal operation.. I doubt I could get more than 15 or 20 30-round magazines fired before nonstop malfunctions occurred, and that's with a NEW weapon hot off the manufacturing line.. I haven't fired other rifles but I'm told that the M16 series is exceptionally vulnerable to this. The AK-47 (just to name one) is rumored to be much more resilient. 11:10, 21 February 2007 (UTC)
There are many weapons much better than the M16 in that regard; not just the AK series, but new weapons like the HK416 are a vast improvement, because they use the piston system, not direct gas inpingement, which really limits the amount of carbon build-up you get. Why the military still uses M16s is beyond me. Oh right, it's the money. I almost forgot. It's more important to save money that putting reliable weapons in the hands of our soldiers. How silly of me. Parsecboy 16:57, 21 February 2007 (UTC)

Yes there are many miore reliable thne the m16 but the m16 has come to be a very relible and accurate system that fits what the armed forces needs currently. and with the cost of rearming it would be ridicualsly expensive, and wit the war in iraq right now and all the critism comin nonto that any thing making the price more hefty would be ridiclas. and many people who use ak47's anymore are just armed guerrillas. some nations still use the AKM or AK74. adn the relibilty issues are very long gone. the vietnam era guns had many designed faults by people who new nothing of guns and thought they were just stalling, like putting in a crome lined barrel or using the right amount of powder. and the powder uegene stoner built his on was better then the army decided to use. adn due to lack of cleaning kits and crome lined barrel it mad it easier to jam M16 is only in service because the army brass likes it, and they like it because most of them are in Colts back pockets. Ask a man or woman whos been in the feild with an M16 and they will tell you it sucks. It's very unreliable because it's not ment for combat in a dirty area like the desert. It's only ment for nice clean western cities. It was designed to fight the Soviets in these clean areas and even then it will still jam because of the gas tube. The army wants to keep it because it meets standerds made during the Cold War. Guess what...Cold War's over. And now we are in a shooting war in the desert and we are using unreliable combat weapons. And as for cost, that an easy problem to fix. Phase out the M16 with things like the XM8 and sell the phased out M16s to allied countries. Oh, and one more thing, learn to spell.

Proposed merge with Eugene Stoner

Against. Gene Stoner deserves a separate page simply because the AR-15/M16-series are not his only inventions. --D.E. Watters 04:40, July 19, 2005 (UTC)

Against. This was a tough one, but I feel that it truely does belong w/ the M16. It is a bit involved and specific for a biographical entry. Glaucus 19:45, 24 July 2005 (UTC)

Comment: Should be renamed to something like Eugene Stoner's Design -- Zondor 23:51, 24 July 2005 (UTC)

Against: Strongly against actually. Stoner is not just known for the AR-15 rifle. He also designed the Stoner 63 which was adopted and evaluated in combat in Vietnam. It was decided that, while the design had several points of merit over the AR-15, it was not significantly better to overcome the advanced production status of the AR-15. Stoner went on to design several larger arms for a defense contractor. This is akin to making Thomas Edison a footnote under the heading of the light bulb.--Asams10 23:55, 28 July 2005 (UTC)

Proposed move from M16 (rifle) to M16

discussion in August 2005 about move

I propose this page be moved to M16. On the current M16 page is a link to the Eagle Nebula and MI6. The nebula's main name in this case isn't even M16, but rather 'Eagle Nebula', and MI6 isn't even a M16, but 'M' 'I' '6'. While the nebula may be big, and MI6 looks a little like M16, the rifle M16 is by far and away the most common reference for M16. It makes the most sense IMO, and it will simplify splitting off pages (maybe like 'M16 history'). Ve3 02:47, 2 August 2005 (UTC)

  • Against: Don't know where you got your information but the nebula is M16. Did you even go to the Eagle Nebula page and look at it before making that comment? In addition, M16 is also a plotting board for controlling mortar fire, a peptidase family, a line of knives, a type of connector for electronics, a line of sailboat sails, and the FAA designation for the John Bell Williams Airport in Raymond, MS. Chuck 17:17, 2 August 2005 (UTC)
Did you even go to the Eagle Nebula page? Or read my comment? I said "The nebula's main name in this case isn't even M16, but rather 'Eagle Nebula'";M16 is just one of its names, and not its wikipedia page name, which is currently 'Eagle Nebula'. Anyway, the main point wasn't that there were not other things that use 'M16', but that the rifle M16 is the most common reference for 'M16' (not a 'peptidase family'). However, given there will be so many other m16s eventually, I suppose its pretty much a dead issue. Ve3
Oops, I totally misunderstood your original post. Sorry for the rude comment. However, I still think the disambiguation page should stay as is. Chuck 20:16, 2 August 2005 (UTC)

NPOV, weasel wording, etc.

"it is often recognized as the best assault rifle of its time period and is the paradigm for assault rifles today."

Now, I know quite a few people that would say that about, for instance, the AK-47. Or any number of other assault rifles. It's clearly NPOV, despite the "often recognized" weaseling. 15:59, 19 August 2005 (UTC)

I've fired the M16A2 and I don't consider it as the best assault rifle. The rifle must be clean or you're asking for jams. The ball ammo it uses puts out lots of powder which must be cleaned off. Burst mode is a joke. The elevation wheel traps sand and dirt easily, making it hard to turn. And if you ever drop it, hope there's no live round in the chamber. Finally, no one seems to talk much about the double-feed jam, the worst. --Pelladon 07:00, 9 September 2005 (UTC)

M16 Table issues

Pettifogger, I didn't think the Colt 602 was the XM16. I was pretty sure neither of these rifles were standardized, and that the XM16 the 604, and then when it was standardized as Type A it became the M16. The purchase of the 602 appears to have been extremely limited, and I'm not even exactly sure who ordered them. I've never heard to them referred to as XM16s either. Also, I thought that the distinction between the M16A1 PIP and the M16A1E1 was more defined and that the two rifles should be considered seperate. These were my understandings, that's all. --Thatguy96 21:37, 29 November 2005

There is no reason to have separate columns for US Army and US Air Force designations, since they both used the same names. It also excludes the US Navy and US Marine Corps.

I felt that the Model 601 and Model 602 were different enough to have separate entries.

The XM16 was the Model 602, not the Model 604. "The 02 is the initial version of the M16 rifle. Some were marked with the US Property marking. These were referred to as the "XM16", with the "X" designating "Experimental." [1]

I changed S-1-F to Safe-Semi-Auto or Safe-Semi-Burst, since it is more obvious to the unlearned reader, and it reflects what is actually on the rifle. I don't know of any firearm publication that uses S-1-F. It does not significantly affect column width since "Trigger pack" was much longer than S-1-F.

The rifling twist was added, since that is different than profile.

The front sight type was added as a column since that does vary. For the M16 and M16A1, it was a round post with five positions. For the M16A2, it was a square post with four positions. The M16A2E1 Enhanced Rifle and Model 656 sniper rifle also had different front sights.

The open-ended three-prong flash hider and the birdcage were both used on the M16, XM16E1, and M16A1. The M16A1 was officially type-classified on February 28, 1967. The birdcage flash hider was used on all M16 production starting in January 1967. {{ref|BlackRifle}1}

The M16A1E1 is the same thing as the M16 Product Improved Program. "For identification purposes the PIP rifles were designated the M16A1E1.' [2] The next page has a picture captioned "One of the 50 Product Improved (PIP) rifles, called the 'M16A1E1'". Since the M16A1E1 was a transitional item, there are pictures of them with a mix of M16A1 and M16A2 features.

Just so that it's clear, there were substantial purchases of the Model 602 AR-15 by the USAF. That's why they got stamped Property of US Government, and why they were issued as AR-15s, not M16s. This was before contract DA-11-199-AMC-508. The specifications for the USAF manuals for the "RIfle, AR-15" state the rifle barrel is 1/12 twist, which means it's a Model 602 Colt AR-15, not a Model 601 Colt Armalite AR-15. I believe the NSN for the Model 602 was 1005-00-939-0584. Pettifogger 02:25, 2 December 2005 (UTC)

"Major" Users

The list of major users seems to be vastly overblown. A lot of the countries listed have their own weapons manufacturers and the standard issue rifle is not (and never was) the M16 (Germany, France, ...). Other countries have since moved on to other, more reliable rifles and are not using the M16 any more (Australia, New Zealand). I think this section needs a cleanup or at least some references. 19:13, 31 January 2006 (UTC)

This is according to Colt. I'm not sure about Germany, but French Special forces are definite users of the pattern, and continue to be. You can find pictures of French SF in Ivory Coast with a smattering of FAMAS G2s, AR-15/M16 type weapons, and Sig-Sauer SG550 type weapons. The Australian SASR continues to use the pattern (primarily M4s manufactured by Colt), despite the change on the official army level to the ADI F88 (the locally produced Steyr AUG clone). This is also the case with the British SAS, who refused to adopt the original SA80 series weapons, preferring to stick to this pattern and other stock weapons instead. I can't find a single country on the list besides Germany that I find fault with. It may not be front-line use, and it may not be the majority of that countries weapons, but all of the countries on the list field the pattern in some capacity. Thatguy96 15:34, 31 January 2006

Holy POV batman

Good god the m16a2 section is POV. Someone apparently doesn't like it. I cleaned out some factually incorrect information there, as well as the most blatantly POV statements. I'm considering deleting the entire last paragraph of that section, as it adds nothing to the article whatsoever. SWATJester Flag of Iceland.svg Ready Aim Fire! 16:34, 8 February 2006 (UTC)

  • FWIW: The criticisms of the M16A2's features came straight from an US Army-sponsored report. They really did feel that certain A2 "improvements" were not necessary given the differences between Army marksmanship doctrine vis-a-vis USMC doctrine. A brief discussion of the Mellonics's original 1982 memo can be found in "The Black Rifle". The full report "Analysis of M16A2 Rifle Characteristics and Recommended Improvements" can be found online. --D.E. Watters 02:51, 17 February 2006 (UTC)
  • The problem is that this is one report of the US Army against many other military reports. Full automatic fire has since been discredited as an effective means of suppressing fire in both USMC and Army. With the wide spread use of aimpoints and ACOG's problems with the irons are not nearly as important as before.

Chin, Cheng-chuan

  • The significance of the Mellonics report is that it helps explain the mindset in certain Army circles against adopting the M16A2. The Army did not order significant quantities of M16A2 until a couple of years after the USMC did so. --D.E. Watters 15:14, 26 May 2006 (UTC)

source for m16a4 information

"Program Status. Fielding of the MWS began in FY 2003. and continues through FY 2007, for a total. of 59479 M16A4 and 10407 M4 weapons. Procurement Profile"

[3]. There. 60,000 produced in a year, 50000 more than the m4 counts as significant numbers. As for the firing cycle: If you're seriously disputing that......... Please don't WP:DICK SWATJester Flag of Iceland.svg Ready Aim Fire! 23:12, 16 February 2006 (UTC)

Procured does not equal received or fielded. You state that the rifle has almost completely replaced the M16A2 in country, and you cite nothing to this. To the contrary, reports I've gotten from the Marines is that they've got some, but are mostly using M4's.--Asams10 23:17, 16 February 2006 (UTC)

I did not state that. The person who originally put that stated that. Secondly, I've seen the marines first hand using them, though that doesn't count here. You can check the pictures yourself.,, all have extensive photos of USMC using m16a4's in iraq. Furthermore, you deleted the section about cycle of operation. That's absurd. See this from armalite [4]

Furthermore, you cannot dispute that there are 3 main iterations of the m16. What, does the m16a4 not exist now? It doesn't matter how many are in use, the fact is, it's an iteration of the development, that's all the article states. Finally, marines do NOT get m4's in any large numbers. Any marine will tell you that. Would you like me to go bring some in to post that here? SWATJester Flag of Iceland.svg Ready Aim Fire! 23:21, 16 February 2006 (UTC)

I revised the section. The cycle of operation should NOT be in the initial paragraph.--Asams10 23:37, 16 February 2006 (UTC)

Forward Assist

The article appears to imply that the forward assist was added in response to the M16's reliability problems in Vietnam. That is widely believed, but I think a review of the historical record will show the Army demanded the forward assist be added prior to the reliability problems arising, not in response to them. As I understand it, Army officers demanded some way of closing the bolt manually simply because the M1 Garand and M14 had that ability, therefore the M16 should too.

You are correct on this. The Forward Assist was a feature demanded as part of a whole host of features that were primarily intended to bog the M16 down so much in redesign and alteration as to effectively prevent its adoption. Among other things was a change to .258" caliber. These "Poison Pills" were continually addressed throughout the turbulent adoption process to attempt to derail the gun. This happens to be one that was left in. Whatever advantages (real or imagined) provided by the Forward Assist are negated by its disadvantages; namely, the Forward Assist will cause as many jams as it will prevent, it adds cost and complexity to the weapon, and it makes the manual of arms more confusing.--Asams10 19:47, 27 February 2006 (UTC)
Bull. How are you going to sit here and pretend to have knowledge of the M-16 by saying that the forward assist will cause as many jams as it will prevent? It is an additional piece outside of the receiver which plays no role in the action of the rifle. So what you're trying to say right here, is that adding a little metallic ear, that you can depress from the receiver to force the bolt shut makes a weapon more complex? You my friend have no idea what you're talking about. - Hemi —The preceding unsigned comment was added by (talkcontribs) 05:54, 3 December 2006 (UTC).
You attack me personally without bothering to register. Register this. The forward assist pushes a round further into the chamber. It JAMS it into the chamber when used PROPERLY. This is MORE likely to jam the rifle. Your argument sucks. It does add cost and it does add complexity. It takes two machined parts, a spring, two pins, slots cut into the side of the bolt carrier, a boss on the side of the forging, and two holes drilled into the receiver. Each of these holes also requires a separate fixture and tool. In the factory, two fixtures and two drill presses were used requiring two full-time machine operators, just for the receiver. Please try to do a LITTLE research before you call me on something so you don't look like a fool.--Asams10 00:35, 4 December 2006 (UTC)

Blackhawk Down Poster

I believe that if somebody were to get a screenshot of a scene in Blackhawk Down, then the fair use tag would allow us to use it to illustrate the M16 itself. See Template:Film-screenshot and the justification, "...for identification and critical commentary on the film and its contents," to comment on the use of the M16 in the film. However, I believe that it's a bit extreme to take the poster image down for the reasons given.--Asams10 01:51, 26 May 2006 (UTC)

5.56 less than lethal?

Ranked dead last in lethality? From the report: [5] Is Faulty Ammo Failing Troops? Field Report, Government Tests Raise Questions About Bullet For M-16 Rifle

Odd, a new US Army report would seem to challange that to a degree.

When are you ever going to shoot a person in a combat situation once and wait to see what happens?

There are quite a few stories floating around the Army about insurgents using hallucinatory drugs to keep themselves killing as long as possible.. it's entirely possible that if you're high out of your mind you wouldn't notice the damage a 5.56 round will do, but it is most certainly lethal.. Just to be safe, though, I'd stick with a .50 caliber M2. :P 11:16, 21 February 2007 (UTC)

AR-16 Reference

See page 57 of "The Black Rifle." --D.E. Watters 23:29, 8 June 2006 (UTC)

  • Upon further research, I believe that it may have been the AR-12. The AR-12 and AR-16 are very similar in appearance. The AR-12 was originally supposed to be a stamped receiver alternative to the AR-10, complete with direct impingement. However, after Fairchild sold the patent rights to the direct impingement system to Colt, Stoner modified the gas system to a short-stroke piston design. The AR-16 is really a modified version of the gas piston-eqipped AR-12. You can find detailed photos of the AR-12 in the March '96 issue of "Machine Gun News" and the January '98 issue of "Small Arms Review."D.E. Watters 01:58, 12 August 2006 (UTC)

redundant sections are redundant

There is a lot of information in this article that is repeated further down, and later that information is repeated, such that information that was already in place in one section is also repeated in another section.

In other words a lot of information in this article is repeated later and some of the information appears also in an earlier section. This seems redundant and seems to detract from the overalll good quality of this article. It might be suitable for some of the information to occur in 2 different contexts but it seems that a lot of this has been written without regard to what appears in other sections of the article.

I don't feel I have the expertise to easily recognise where the use of repetition is appropriate and where it is not, however if some expert gun dude wants to attack it, I'd be very glad to pick it over and point out specifically where it seems redundant if help is needed... any takers?

I agree that there's a lot of repeated information in the article, and I think that's the main reason why article size to be longer than the ideal size set by Wikipedia's standard (see Wikipedia:Article size).

Former Rifleman Speaks:

I served ten years as a US Army Infantryman and I have used the M-16A4 in combat in Iraq as well as shot the M-16A2 under every condition imaginable, sandstorms, swamp, rain and snow to name a few. In ten years I never had a '16 jam on me. I have used them to take out point targets from arms length to 600 meters. This rifle is accurate and reliable. The problem with lethality lies not with the the weapons caliber, but the composition of the projectile. U.S troops use a full metal jacket round that was designed to defeat Soviet and Warsaw Pact body armor by utilising a metal jacket and a steel or tungsten core. In the War on Terror, we need to switch to a soft lead "hunting" type projectile that will mushroom and fragment on impact, creating a greater shock effect by transferring more kinetic energy into the enemy. What happens now is when we shoot coked and methed-out insurgents with these full metal jacket rounds is that they pass right through them like a hot knife through butter. They eventually die from blood loss or infection, but they can still be dangerous. When I was in the Battle of Fallujah in November 2004, we figured out that if we aimed low and tried to hit insurgents in the hips or the legs, they dropped like rocks. Once they were down we could finish them off or use the wounded to bait their buddys. Many times I saw 5.56mm accidently skip of the pavement and into the shins and thighs of insurgents. Also the best M-16 variant is the M-4 carbine. You get all the advantages of a close combat weapon that can be fitted with any number of sighting aids, lasers and tac lights and still get pie plate sized groups at 300 meters. Also, I favor iron sights over M-68 red dot sights or ACOGS, I don't trust a sight that needs batteries. In close quarters I believe in "fingers and toes" sighting. —The preceding unsigned comment was added by (talk) 23:02, 26 Septmeber 2006.

  • You were active for 10 years and never had to use immediate action on your weapon? Additionally, you seem to be under the false impression that an ACOG needs batteries. I'm skeptical of your claim to have been in the Army at all, let alone spending 10 years as Infantry and serving in combat. ALL automatic firearms jam. The M-16 and its variants are no exception. When properly maintained, it doesn't happen very frequently, but it does happen. EvilCouch 10:49, 6 October 2006 (UTC)

I never said that I'd never seen or heard of one jamming, I said I never had one jam on ME. Now I have had to apply SPORTS a time or two to get a fully loaded 30 round mag going, but after that it never jammed unless I had a dud round. Yes, the ACOG does not require batteries, I was referring to the M-68 red dot style scope that require a lithium battery to operate. I still preferr iron sights above all because that's what I was weened on and they have the least amount of things that break or need adjusting. As far as my own service with the United States Army, its a matter of public record: Epps, Matthew W last 4 8402. Look it up. Oh, and Mr. Couch, you failed to mention what branch YOU served in. Your lack of attention to detail pertaining to what I wrote suggests you might be a cake eater. Don't get the wrong idea, I'm not angry with you, there's one "Soldier of Fortune" wanna-be who likes casting doubt on other peoples service to compensate for their lack of testicles in every bunch.

No hard feelings here, it never hurts to check someones bonifides. Since I got out I tend to take stuff personally, I blame it on PTSD...LOL. 1-503rd is out of Camp Red Cloud ain't they? I get all those Korea posts mixed up. I never actually went to Korea, but in ten years I heard every Korea story there was. From soju to the midget and "mom". Joke: How many Rangers does it take to change a light bulb? A: 3, 1 FNG to change the lightbulb and 2 old timers to stand there and talk about how hard it was when THEY had to change it. Now the M-60 machine gun, those damn things jam. I was a 60 gunner in 2-2IN 1ID in Germany just before we got 240-bravos, that damn thing jammed every 10 or 12 rounds.

We should take this over to a personal talk page, as we've gone off topic. I openned up your talk page, although we could just as easily use mine. EvilCouch 10:43, 13 October 2006 (UTC)

He didn't say the ACOG needs batteries. He says he prefers iron sights over m68s and acogs, and seperately that he doesn't trust a sight that needs batteries. In 5 years in the army infantry, I've rarely had an M16 jam on me, and the times it did were due to faulty ammo or faulty magazines, not the rifle itself. When cleaned religiously like any good infantryman does, it's a great piece of work. SWATJester Ready Aim Fire! 05:30, 11 October 2006 (UTC)

I served ten years as a US Army Infantryman and I have used the M-16A4 in combat in Iraq as well as shot the M-16A2 under every condition imaginable, sandstorms, swamp, rain and snow to name a few. In ten years I never had a '16 jam on me.
I stopped reading there - you, sir, are a fake. I see that other people have already blasted you for it, though, so I'll save my breath. It's sad when a freaking 25B (a COMPUTER guy) in the Army can see through this shit. We get probably the least combat exposure out of anybody. 11:18, 21 February 2007 (UTC)

Former Rifleman: Perhaps if you pogues (Personel Other the Grunts) would clean your rifles regularly then you wouldn't get jams. If you like, go to and check out my pics if you think I'm a fake. As I have stated before I have seen M-16's jam due to old, worn out magazines, dud rounds or failure due to fair wear and tear. However I stand by the claim that I have never experienced a jam with the M-16A2, M-16A4 or the M-4 on a rifle range, live fire excercise like a Table XII or in combat. The only malfunctions I experienced were intentional malfunctions caused by putting spent casings into a magazine to simulate a malfuction during BRM back on Sand Hill or for EIB testing. I also stand by the claim that a well maintained, clean and properly zeroed M-16 in its current form is a very accurate and reliable weapon though less lethal that I'd like with current issue ammunition. P.S.: Be sure and leave me a message on myspace you litte Fobbit. —The preceding unsigned comment was added by (talkcontribs) 08:54, March 25, 2007 (UTC)

Dudes, did you read what the former rifleman actually said? Maybe if you would have read a bit further, you would have seen that he only said that one had not jammed for HIM. Also, what do you mean by a "jam"? We may be talking about different things here. Are you only considering a double feed or stuck casing as a jam, I do? Or do you also consider stovepipes and most types of misfeeds to be jams, too? See, I would consider stovepiping and some misfeeds to be MALFUNCTIONS, not JAMS, because you don't have to pull out tools or anything special to take care of the problem. Maybe that is just me, but two people reading the word "jam" might have different ideas of what a jam is. I have experienced a number of malfuntions during my time in the Army (25 years, including M16s, A1s and A2s), but never an actual JAM personally, though I too have seen them.

Delisted GA

Forget inline citations, the vast majority of this article is compleatly unreferenced. How is anyone supposed to tell whether the five things at the bottom actually cover this increadibly expansive and detailed article? I also don't see any sign it was reviewed in the first place, which is problematic. Homestarmy 16:09, 27 September 2006 (UTC)

Uh, we can tell that the books listed cover this article by READING THE BOOKS. If you want somebody to go statement by statement and reference EVERY point made, you can keep your "Good Article" status away from here. It's referenced, it's just not an AMA article.--Asams10 05:46, 5 January 2007 (UTC)

No XM16?

Okay, now I'm confused. How is it possible to have an XM16E1 if there isn't an XM16? Shouldn't it have then been XM16? How can you have a subvariant of a variant that never existed? -- Thatguy96 22:55, 10 November 2006 (UTC)

The Air Force version of the XM16 was the AR-15. The Air Force didn't use Army terminology. In reality, the XM16 existed, at least on paper.--Asams10 23:29, 10 November 2006 (UTC)
Well that was sorta my point. XM16 had to have at least been a "paper" designation, because there would be no way the Army would've gotten to XM16E1 without the distinction. I guess I could still be wrong, but this would seem logical. -- Thatguy96 01:25, 11 November 2006 (UTC)

Reasons for more detailed introduction

The biggest single reason, is that to simply talk about the M16 is not accurate, becuase it is not the designation for the whole family. The article is actualy about 4 distinct military eqipment items, each with their own history and details. If just 1 designation is listed, it is just not correct.
Another is that having a short introduction is common literary practice, becuase later information can be too detailed for key information. The second overview is more accurate but also longer, and the same can be said for the even larger sections farther down in the article (redundant, but more detailed).
In the long term the introduction can be both shorter and accurate, but this cannot be achieved by removing the other rifle's designations. I don't mean about the previous XM16 issue brought up by DE, but the mentioniong the A2/A4 etc. The NATO and ammo can probably be trimmed back also, but I leave that to others. Ve3 17:45, 11 November 2006 (UTC)
Wait are you kidding me? Or am I really reading you say the "M16 is not accurate." The M-16 is the most accurate semi-automatic rifle ever created. If I'm not reading correctly, sorry about that but if I am, you my friend need to stop playing video games and research this rifle more. - Hemi —The preceding unsigned comment was added by (talkcontribs) 05:47, 3 December 2006 (UTC).
He didn't say the M16 wasn't accurate. Please do not personally attack other users when you can't even read their comments correctly.--Asams10 00:41, 4 December 2006 (UTC)

Also, don't say that it is the MOST accurate. I am sure that some other stock semi-auto weapons (possibly even the M1 Garand or M-14, though I haven't checked that personally) are more accurate than the M16. Stay away from the hyperbole when you say something. AK person 17:59, 21 March 2007 (UTC)

M16 Barrels

I erased the "The 30-round magazine is not suited to sustained fire like the belted feed systems of heavier true machine guns, and the M16's lightweight barrel would overheat quickly under automatic fire." because of blatant bull.

The M16 is issued as an HBAR, meaning HEAVY BARRELED AUTOMATIC RIFLE, therefore it automatically proves who ever wrote this doesn't know what he's talking about.

The 30 round magazine is also VERY suited for sustained fire, especially because the M249 Squad Automatic Weapon (Light Machine Gun) is capable of being belt-fed or fed through an M-16 magazines. —The preceding unsigned comment was added by (talkcontribs) 05:47, 3 December 2006 (UTC).

Once again, you read the section you removed incorrectly, Neither the M16 nor the M16A1 are heavy barreled. The M16A2, A3, A4, the M4, and the M4A1 are all light contour under the handguard and overheat quickly. The reason for the 30-round magazine comment is that frequent mag changes required with the 30-round magazine make it unsuited for sustained fire use needed for suppressive fire. I'm putting the section back. Once again, sign your comments. --Asams10 00:46, 4 December 2006 (UTC)
Just because the M249 SAW was designed to accept standard 30-round or 20-round magazines AS AN EMERGENCY MEASURE does not mean that the magazine itself is specifically designed for or practically suited for sustained fire.. Anyone who has EVER fired a M249 in the United States Army will tell you the same thing - loading a magazine into it is asking for trouble (ie jams). Not that a 30-round magazine would last you long enough to make it worth the trouble of loading in the first place. The SAW eats through ammo like a monster. And it's designed for belts. Don't get it twisted, our weapons aren't nearly as reliable as the manufacturers and defense contractors would like the general public to believe. 11:24, 21 February 2007 (UTC)

Plus the 30 round mags in the m249 jam generally after 3 or 4 shots. I know, I was a SAW gunner for 2 years. SWATJester Ready Aim Fire! 03:11, 4 December 2006 (UTC)

Jester, I'm not sure if the magazines are to blame for the issues. I carried an M240G in Fallujah, so I was qualified with the M249 as well. The condition of the M249s in service probably play the biggest role in their performance. I've fed an M249 with plenty of 30 rounders, and they worked fine. A casual FTF once in a while, but the same happened when I belt fed it. - Hemi

The M-16 hasn't been used in the automatic rifle role since the M-249 SAW came out in the 80's. I too have a number of years experience with the SAW and I have found that it's performance with M-16 magazines depends on the condition of the magazine itself. If the magazine is old and unserviceable, like many magazines are because either Joe is too lazy to get some new ones then the old ones were out, or the armorer can't get any, then you get a greater number of jams. The precribed sustained rate of fire for the M-16 is between 10- 15 rounds per minute if you want to hit anything. Remember, suppressive fire only suppresses if it's accurate. So that's why every rifle squad now has two saws, one in each fire team. The saws along with 7 rifles and 40mm grenades can provide a nice base of fire for the platoon to manuever off of. This is especaially true when you add one of the platoons machine gun teams laying scunion on the bad guys with the M-240B

Why isn't the R in Rifle capitalized...

The first letter after a number is supposed to be capitalized and M4 Carbine... What's the deal, eh? Deathbunny 10:15, 11 December 2006 (UTC)

House Cleaning

I went through and purged unnecessary, duplicate, and commercial links. There are TWO lists of see-also's and many of these were also listed in the text. Not very organized or efficient. --Asams10 15:33, 14 February 2007 (UTC)

I think M16/203 is better than only M16. Only because of HE grenade. —The preceding unsigned comment was added by (talkcontribs) 13:13, February 18, 2007 (UTC)

Maybe, although you trade off for those grenades. The 203 is rather awkward (in my opinion), and it adds just a wee bit of weight to the total weapon, plus you have to carry at least a few grenades. The 203 firepower is nice to have in a fight, but I'd let someone else take it to the fight if they want it. —The preceding unsigned comment was added by AK person (talkcontribs) 18:05, March 21, 2007 (UTC)

Original Research

My modifications were the addition of the LSA and the poorly hardened 20-round magazine comments, based on my experiences in Vietnam, 1967-1970.

OOPS! The last comment was by Rhilliam 18:16, 4 April 2007 (UTC)

Original research was removed. Good info, but without a reliable internet or written source, your anecdotal evidence is as good as anybody elses. It's true, troops downloaded the magazines, but welding and riveting processes were to blame, IIRC, not heat treating. --Asams10 21:00, 4 April 2007 (UTC)

My comments have been restored, and will continue to be restored whenever deleted, as they are nothing less than the truth. Not to mention first-hand experience. Another tid-bit about the "comic book" is that the central character in these booklets was a buxom blonde named Chris Noel. These frequently-issued "comic books" covered ALL aspects of the grunts' life in 'Nam, not just the M16. Instructions on maintaining the M16 were also frequently aired on both AFVN radio and television.

The M16 magazine used NO welding and NO rivits in its construction. It was made up of 4 pieces: the shell, floorplate, follower, and spring. The shell was stamped and folded into a box with the crimped joint on the back side. The floorplate was removeable (it slid to the rear) to allow the magazine to be disassembled and cleaned. As an "anecdote", for I have no real proof of this, the reason for the inadequate heat treating was that McNamara and his "Wiz Kids" figured to save a few cents on each of the millions of magazines. They thought that us lowly, uneducated GI's were to stupid to remember to hang on to them when empty, and would just drop them in the dirt, so why spend the extra money on a single-use magazine? At least one of these "comic books" dealt with this. In its pages it contained a picture of a smiling, black-pajama-clad VC with the words "VC SUPPLY" on his conical grass hat crawling through the elephant grass picking up empty magazines. Our buxom blonde says "Hang on to 'em, boys!"

LSA was similar in consistency to hand lotion and a pale yellow in color. It was issued in a soft plastic bottle similar to an Elmer's Glue bottle. It was truly good stuff, and especially useful on the M60 machine gun, also called "The Pig", and for good reasons.

My first M-16 in January 1968 was an M16A1. The rifle I was issued in November 1968, when I began my second year over there in a new unit, was a Colt-made M16E1 with the three-prong flash suppressor. I had it until October 1970, and always kept it clean and never had any trouble with it. My primary weapons were the M60 (a real piece of junk), the M79, and the M2 .50 caliber, standard armaments on the M113 ACAV.

I'm not going to argue if you're going to misrepresent the truth. You use the weapons, but are you an engineer? The M16 magazine has three rivets to hold the steel reinforcement on the front and five spot welds along the rear. You are violating Wikipedia rules and your edits will be reverted. If the information is that important, it certainly appeared elsewhere. Frankly, I can't find were and I've got about every Magazine variation from that era for my own original research. --Asams10 14:15, 5 April 2007 (UTC)

I added a Mil-Spec for LSA. An internet search on that number, or m16 +lsa will give you all you want on the stuff, including where to buy some, plus many "anecdotal" stories. One web site even had some pages out of the "comic book" mentioned in the Wikipedia M-16 article. When time permits I will add an external link to some of the better sites. I also intend to dig up some stuff on the magazine construction and the "comic books". Maybe I will do a Wiki article on them and introduce everybody to Chris! Rhilliam 18:18, 5 April 2007 (UTC)

I forgot: I noticed that this article has been removed from Wikipedia's "Good Article" list. I wonder why? Rhilliam 18:21, 5 April 2007 (UTC)

Hmmm, could it be a lack of citations, original research, etc? I don't wonder, myself. --Asams10 19:58, 5 April 2007 (UTC)
While you may find what you want using a Google search, it might not be apparent to readers to do a Google search. It's best to find a source via Google and then use that to attribute your addition. Wikipedia does not allow original research. x42bn6 Talk 20:19, 5 April 2007 (UTC)
Online sources may or may not be reliable, but see for the LSA claim, and for the jamming. -- BenTALK/HIST 04:04, 6 April 2007 (UTC)

You don't remove stuff upfront. You only remove it *if challenged*, and I don't see any reason to challenge Rhilliams assertions (except for the bit where someone challenged about the rivets, which is a separate story). --Kim Bruning 20:50, 5 April 2007 (UTC)

Uh, it was challeneged. I'll explain in more detial. The welds on the aft edge of the magazine were insufficient and tended to break under use. Similarly, the rivets holding the steel plate in the front of the mag would rust and fail causing a catastrophic failure of the magazine. In years of original and secondary source research, I have NEVER found anthing to substantiate ANY problems with the metalurgy of the magazine. Most of the failures were due to rough handling and overloading.--Asams10 00:18, 6 April 2007 (UTC)
Fair enough. And if some folks *did* have issues with the metalurgy, perhaps it's still documented someplace, right? --Kim Bruning 02:54, 6 April 2007 (UTC)
I did the google searches for s&g, but nothing came up. The LSA issue was not new for the AR-15 nor was it the important factor. Proper cleaning fluid was availabe in supply, but wasn't issued as a rule. Cleaning EQUIPMENT was another story. Stoppages were also not generally due to fouling (as the grunts thought) but rather to unplated chambers creating pits that the slightly tapered cases expanded into, exponentially increasing friction on the chamber walls. I've got the original reports somewhere in my stacks. Too much to get into with this article, though. Suffice it to say, I strongly disagree with both the tone and content of the original research in question. --Asams10 06:09, 6 April 2007 (UTC)

Did any interested parties have a chance to Google the items in question? I got over 25,000 hits on m16 +lsa, and 149 on MIL-L-46000. Look at Also, a copy of MIL-L-46000 is available from the GPO for a small fee. The lack of cleaning equipment that Asams refers to was a very real 1965 problem, as was the chamber size. These guns were withdrawn by mid-1967 and shipped back here for use in training. I briefly had one in AIT. With the issue of an M16 in early 1968 also came a canvas pouch that clipped to the web belt and contained a bipod, sectioned cleaning rod, eye-loop, bore brush, locking recess/chamber brush and a bottle of LSA. I also got 617,000 hits on M16 +magazine. The thing is a collectors item all on its own. It'll take some digging to satisfy Asams, but it's there. And yes, there are welded steel mags today. And don't forget Chris Noel.

Again, no, it's welded ALUMINUM. Five spot welds on the rear. There is a steel reinforcement strap on the front of the magazine tacked on with three rivets. That's why there's a groove in the front of the mag well, to allow room for the rivets. I'm not talking about steel magazines, I'm talking about the Military Specification 20-round magazines issued to troops during Vietnam, replaced in the 70's with another welded magaznie. WELDED... WELDED. Please, if you don't know what you're talking about, don't attempt to debate the subject. This is tedious. --Asams10 23:06, 6 April 2007 (UTC)

Hold your hands out crossed in front of you, directly over one another. One palm up and one palm down. Bend the fingers of each hand 180 degrees and then hook them together. Imagine running them between two wheels. What you have is a crimp Crimp CRIMP. Another anecdote. A few of us were sitting around one day discussing the cheap crap (don't get me started on the M60 machine gun!) we were expected to fight the war with. One fella (I remember his name, too) took the floor plate off a magazine, dumped the innards out, laid it flat on a sandbag and smacked it (and none too hard, either) with his fist. The magazine sprung apart. I AM compelled to concede that what you describe may have been introduced after my time (10/70 or later), but that makes my observations (and modifications to this Wiki article) no less valid. Below is a few of the 236,000 hits on steel magazines for the M16:

Another anecdote: A couple years ago on the History Channel was a program on the evolution of US Cavalry units, form the Civil War on up to today. Included in this program was a brief history the 11th Cavalry/11th Armored Cavalry. The narrator said that the 11th Cav served as a heavy artillery unit during the Vietnam War. Wow! I guess what I thought I did never really happened. Or maybe we can't believe everything we see on TV...

Rear Sights on the A4

Perhaps some mention should be made of the flip-up rear irons on the A4 model in the article. It's meant to be used with a scope mounted on all those rails hanging off it, but the irons installed should be mentioned in the article. If I had my druthers I wouldn't use them as a -main- sighting system, but they do in fact work pretty well in my limited experience. Kensai Max 02:01, 26 April 2007 (UTC)

I think you'll find that BUIS, even on rifles that have optics fitted, are far from standard. In fact, the two pictures of M16A4s in this very article with optics fitted don't appear to have BUIS. BUIS is not mentioned in the Army TM for the M16 series as being part of the included equipment either. Standard rifle sights for the M16A4 are supposed to be provided by those on the detachable carry handle. -- Thatguy96 02:28, 26 April 2007 (UTC)


Why does someone keep deleting my statements saying the M16A1 is still in use? It still is, see the List of Individual Weapons of the US Armed Forces, it lists the M16A1 as "still used in limited numbers". QZXA2 00:37, 28 April 2007 (UTC)

Okay, now I'm confused at the edits too. I have not seen it be "widely" used by any NG units, and police agencies and foreign armies should warrant a short sentance like the one I had included. Regardless, I don't see why my edit was removed without replacing it with something similar to what exists at the end of the M16 subheading. -- Thatguy96 00:55, 28 April 2007 (UTC)
Not only by the National Guard, but by the US Air Force and by countless agencies around the world. Your edit was wrong, that's why I reverted it. If you want to say that it's no longer used by the Army or Marines in front-line service, feel free to say that, but there are still hundreds of thousands of M16A1's in regular service. --Asams10 01:12, 28 April 2007 (UTC)
I'd really like to see a picture. I can't find a single one of an Air Force security police member with one past 1998, and I haven't seen any NG with them since around the same time period. Still in arsenals maybe. Called out for basic and the rest of it maybe. But regular service? Inactive NG units theoretically equipped with them isn't regular service in my mind, and almost every NG unit I've seen deployed to Iraq has M16A2s. I'd just like to see a source. -- Thatguy96 01:16, 28 April 2007 (UTC)
The source is me... I'd like to see a source saying they have been essentially retired. IIRC, it's proper to revert any unsourced material if it's believed that said entry is erroneous. If the M16A1's have been retired, great. Give me a source and I won't have any concerns.--Asams10 01:34, 28 April 2007 (UTC)
I never said retired, I said a source for it being in regular service with NG units. In an arsenal with an inactive guard unit doesn't exactly qualify in my mind as regular service. I have seen no pictures of guardsmen and women in combat zones with A1s. Fyrthermore, unless we can cite you saying the source is you gives me just as much reason to revert unsourced material. If the source is you then I can't imagine you don't have a picture. -- Thatguy96 03:44, 28 April 2007 (UTC)
Asams10, you cannot use yourself as a source, that's original research. You must have a documented source stating that A1s are still in front-line service. You have as much of a burden of proof as Thatguy96 does. As for my personal experiences with National Guard troops over in Iraq, I've never seen any of them with A1s. All of the NG soldiers I've ever come in contact with have A2s or M4s. In fact, the only A1s I've ever seen were the "rubber duckies", which hardly count. Parsecboy 08:47, 28 April 2007 (UTC)
While I'm here, here's a document from the Chief of the National Guard Bureau, with a section on essential soldiering tasks, that lists maintenance of the M16A2 (among other weapons, but lacking the A1). Here's a list of standard equipment for hte Kansas ANG, listing only the A2. Here's an article from 2003 stating that the NG has 80k (not "hundreds of thousands) A1s, but they are "outmoded weapons classified as nondeployable", which doesn't exactly have the same meaning as "regular service". Even if we use just a simple google query, we get over 11 thousand for "National Guard"+M16A2, and only 535 for "National Guard"+M16A1. Seems that you're wrong, Asams10. Parsecboy 09:07, 28 April 2007 (UTC)
I didn't cite myself as a source nor can you cite a google source. Find a source that lists how many M16A1's are in service worldwide and I'll concede. In the meantime, sourcing myslef is as good as the original unsourced content. Leave it out or leave a source. I'll finish my book when I'm retired, then I'll use that as a source. For now you'll have to find your own sources to counter me.--Asams10 17:37, 29 April 2007 (UTC)
"The source is me..." Isn't that citing yourself? Furthermore, we're not talking about service worldwide, we're talking about in the US military. The edits you reverted said "widely used abroad." Are you saying that only you should be allowed to make that claim? We have sources for what you initially asked for and its somehow not good enough. -- Thatguy96 17:40, 29 April 2007 (UTC)
No, I didn't cite or reference myself. The information came from my mind, collective research over decades. Citing myself would be putting a footnote or saying, "In my opinion" or something silly like that. I may be a little conceited, but I know the information is wrong and should not be included without a reputable source that would prove me wrong. I wouldn't have reverted it if I felt it was correct. Further, if you're trying to limit it to the US Military, I'd agree. However, what I reverted didn't say that. I didn't add the qualifying phrase, "In the US Military" myslef, however I wouldn't be against somebody putting it there. It's true... of the US Military. The M16A1 is rarely if EVER used on the battlefield in Iraq or Afganistan. Nor is it used stateside for much of anything. Notable exceptions are in the US Air Force, the National Guard, and police agencies nationwide. I'd estimate the number of 'front line' M16A1's to be between 50,000 and 100,000 in the US, and around half a million worldwide based on my research. That doesn't include a sizeable war reserve quantity in storage. That's not insignificant though.--Asams10 17:48, 29 April 2007 (UTC)
You cited yourself for purposes of this debate. When asked for a source you gave yourself and then asked us for ours. Someone else provided sources and you see no need to use your "collective research over the decades" to refute the point in the slightest. We're supposed to assume you're right because you say you are. That's not a functional way to proceed in a debate like this. What do you want us to say to that you haven't said to our points? Its hypocritical at the least. You have attempted to compare statements like "regular service" with "sizable war reserve quantity in storage" without providing a single source besides your anecdotal claims and estimations, which bothers me. Especially since we have a published newspaper article that suggests that those 50-100,000 weapons you talk about might well be "outmoded weapons classified as nondeployable."
There's also nothing to suggest that the USAF has done anything with the hand-me-down M16A1s it recieved besides build them into other things. I think this hardly qualifies as regular usage when the associated parts go to keeping M16s and frankencarbines together. Air Force Instruction 36-2226, Supplement 1, dated 23 August 2004 lists two M16s, M16A2 (NSN 1005-01-128-9936) and M16 (NSN 1005-00-856-6885). It makes no mention of the M16A1 at all. It makes mention of all sorts of things a USAF base commander might have in inventory such as Uzis and Mini Uzis (NSN 1005-ND-149-176L and NSN 0000-01-259-2894 respectively), M4E2 carbines (1005-01-383-2835), even AN/M8 pyrotechnic pistols (1095-00-726-5657). Am I supposed to believe if they even had one M16A1 in inactive storage that it somehow wouldn't make the list?
Also, here's what you reverted "The M16A1 remains in service in extremely limited numbers, mainly as a training aid. It has, however, been widely exported abroad." Now I can understand removing what you saw as offensive in the first sentance, but you removed what you continue to say is true in the second sentance as well. You're contradicting yourself. It either has been widely exported abroad or it hasn't, but you seem to say when I say it its wrong, but when you say it is its right. Please excuse me if I feel my points haven't gotten appropriate consideration. -- Thatguy96 18:22, 29 April 2007 (UTC)

Thermal conductivity of in semi-automatic firearms

Okay, short lesson in heat conductivity. This discussion is limited to autoloading rifles. Fully-automatic firearms fire at a rapid enough rate that the heat generated by firing a cartridge is transferred to the bore directly by friction, heat transfer, and pressure and indirectly through the 'whipping' of the barrel as the projectile goes down the bore. The 'whipping' of the barrel causes heat in the same way as rapidly bending a piece of aluminum back and forth will cause it to heat at the crease of the metal. This heat moves to all metal parts of the barrel and firmly contacting the barrel including the chamber, sights, receiver, and bolt face when it's in contact with the barrel. This heat is also transferred to anything that is directly adjacent to the barrel through infrared heat. There are a few other minor mechanisms for heat transfer I'll leave out. Heat is removed from the firearm through several means as well. Among these, there is the aforementioned infrared radiation but direct contact with the air is the major means of cooling a barrel.

Common materials for cartridge casings do not transfer heat to the chamber wall in any significant quantity. They have the following thermal conductivity expressed in celsius (W/m K): Brass= 109, Steel= 46, Aluminum= 250, Plastic (PTFE)= .25.[7] Now, the mass of the metal also counts. While aluminum transfers heat better, there is significantly less mass (weight) in an aluminum casing. Observation of ejected cases will note that both steel and brass are hotter than aluminum or Plastic. The plastic is, indeed, cooler, however the other materials are just as hot, the Aluminum cooling down quicker might not seem as hot though.

The above observation has led to the logically incorrect leap that casings pull heat from the chamber. This is incorrect. In fact, the casing heats up to significantly higher temperatures than the chamber due to direct contact with combustion gasses. This is true until heat from the bore of the firearm transfers heat to the chamber area after, say, 100-200 continuous shots. At that point, the chamber will be hotter than the freshly fired case. Counter-intuitively, the case of the cartridge acts as an insulator for the chamber and prevents it from being in direct contact with the heat and pressure of combustion. Except for heavy machineguns, modern autoloading rifle cartridges utilize their casings for insulation rather than heat absorbtion. In this respect, all of the metal casing materials fail. While they absorb a small portion of heat from the chamber, this heat is not significant enough to cool the barrel even in this instance as they generate more heat from the next shot than they remove from their contact with an already overheated barrel.

Adverse effects from excess heat start with safety. There is a danger that a cartridge left in the chamber after a long string of full-auto fire will heat to a point high enough enough for what is called a cook-off whereby the priming materials in the primer detonate without being struck by the firing pin. Again, brass is a less-than-optimum choice as it transmits heat built up in the chamber readilly to the primer. Rather than lessening the chance for a cook-off, it increases those chances as do the other metalic material choices. In the end, there is no special advantage or disadvantage in terms of thermal transfer with regard to various metalic choices. While PTFE cases offer advantages, they have numerous disadvantages as well, not the least of which are their shelf life and the need for a larger chamber.--Asams10 13:53, 29 April 2007 (UTC)

Um...ok? Parsecboy 15:46, 29 April 2007 (UTC)

Okay, if your comment isn't vandalism, why are you interjecting NOTHING into what I said? I wrote an essay describing why I took out one phrase of content in the article. Um...ok? is either trite, taunting, or ignorant. I'd call all those vandalism. After you got in a fit over the M16A1 service issue above, I feel that you only commented here in an attempt to taunt. --Asams10 17:41, 29 April 2007 (UTC)

I saw no point in your post. It seemed you were posting your comment for the heck of it. You never connected it to an edit you made in the article. How, praytell, did I get into "a fit" about the M16A1 issue above? Because I disagreed with you and provided sources to support my position? Perhaps you shouldn't take things so seriously. Parsecboy 17:45, 29 April 2007 (UTC)

See it how you will, my point was that since you DID get in a fit about the M16A1 edit, I'd post a detailed reason for removal of the content I removed this time. My exact edit title is listed here: [8] So, I don't explain my edits and I get beat up in talk. I do explain my edits and you taunt me? I don't believe I can please anybody. --Asams10 17:51, 29 April 2007 (UTC)

I'm still lost as to how you say that I got into "a fit". Because I rightly stated that using you own experiences, not reliable sources, is original research? That you have as much a burden of proof to support your claims as does Thatguy96 does? Perhaps you need to break it down for me, because I obviously do not understand your logic. But back to the point. I posted my original reply to your original post in this thread because you made no connection between it and an edit you made. Perhaps you should try a phrase like "Here's the reason I made the edit..." as opposed to just posting a seemingly irrelevant comment to no one in particular. Parsecboy 18:42, 29 April 2007 (UTC)

Um, no. --Asams10 20:49, 29 April 2007 (UTC)

I'm a bit confused, is or is not the M16A1 in any kind of practical of theoretical service with the United States military? QZXA2 22:00, 29 April 2007 (UTC)

No, it's not really in practical service anymore. The Army National Guard maintains around 80,000 of them, but they're classified as "outmoded, and non deployable" (and this was in 2003, so the number is 4 years and all of OIF old). Parsecboy 09:49, 30 April 2007 (UTC)


im just what everbody thinks bbut shouldnt this really be added to AR15, i mean it basicly the same thing as how the ak47 artical is named most people dont even know the differnces. but anyway im just wondering what you people think. and i read somewhere in kipedia things should be named by common names, is that how it works in acutal enxelopedias

Dude, I have no idea what you just said. --Asams10 23:11, 12 May 2007 (UTC)
Translation" Shouldnt this artical be changed to the AR15, its like the AK47 people dont really understand the differnces and i was wondering what you guys think. also i read somewhere on wikipedia things should be named common names, is that how it works in actualy published as a book encyclopedia's?" :} as you can see im fluent in good and bad grammer(ForeverDEAD 19:32, 14 August 2007 (UTC))

Lebanese Army will recieve this weapon

Just read that the US Government will donate around 3.000 rifles (both M16 and M4) rifles to the Leb. Army. Should it be included in the "operator" panel? Then to the left there is a video called "U.S. to ship humvees, rifles and ammo to Beirut".

If you go down to M16_rifle#Production_and_usage you'll see that Lebanon is already mentioned, because they are a user of the M16A1, supplied by US forces during the 1970s. The users in the infobox are a product of people putting their own nations in (at least I suspect) and non-notable users (pretty much everyone but Israel on that list) should probably be removed. -- Thatguy96 14:07, 23 May 2007 (UTC)

M-16 deployment worldwide

The section on M-16 being used by so many armed forces is totally wrong: The link says that those countries have been customers of the Colt Co. for various weapons or weapons systems. It does not say that those nations purchased the M-16, letalone procured them in their artillary. Remove that huge list please. Tri400 17:06, 27 May 2007 (UTC)

Iraqi forces rearming with M16

I see the Iraq part was reverted. I'm going to change it back since it is planned and in the process of happening (albeit very slowly), but not without posting the following news story here. This was reported by most of the major players (BBC, CNN, etc). -- Thatguy96 05:15, 2 June 2007 (UTC)
