"AR-15" redirects here. For other uses, see AR-15 (disambiguation).
AR-15 style rifles come in many sizes and have many options, depending on the manufacturer. The part shown bottom center is the lower receiver without the receiver extension, rear takedown pin, and buttstock.

An AR-15 style rifle is a lightweight semi-automatic rifle based on the ArmaLite AR-15 design, which is itself a scaled-down derivative of Eugene Stoner's AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the U.S. patent 2,951,424 and trademarks to Colt's Manufacturing Company in 1959, but after Colt's gas operated bolt and carrier system patents expired in 1977, Colt retained the trademark and is the exclusive owner of the "AR-15" designation.[1]

The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features.[2][3]

After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports Foundation, a firearms trade association, it was quickly adopted by much of the industry.[4][5]

In the 2010s, AR-15 style rifles became one of the "most beloved and most vilified rifles" in the United States, according to The New York Times. The rifles are controversial in part due to their use in high-profile mass shootings[6], despite being used in less than 4% of all gun related homicides. Promoted as "America's rifle" by the National Rifle Association, AR-15 style rifles' popularity is partially attributable to proposals to ban or restrict them.[7][8][9]

Terminology

The Colt AR-15 is closely related to the military M16 and M4 Carbine rifles, which all share the same core design and have the same operating principle. The term "AR-15" is now most-commonly used to refer only to the civilian variants of the rifle which lack the fully automatic function.[10]

In 1956, ArmaLite designed a lightweight selective fire rifle for military use and designated it the ArmaLite model 15, or AR-15.[11][12] Due to financial problems and limitations in terms of manpower and production capacity, ArmaLite sold the design and the AR-15 trademark along with the ArmaLite AR-10 to Colt's Manufacturing Company in 1959.[13] In 1964, Colt began selling its own version with an improved semi-automatic design known as the Colt AR-15.[14] After Colt's patents expired in 1977, an active marketplace emerged for other manufacturers to produce and sell their own semi-automatic AR-15 style rifles.[1] Some versions of the AR-15 were classified as "assault weapons" and banned under the Public Safety and Recreational Firearms Use Protection Act in 1994 within the United States. This act expired in 2004.[2][15]

In 2009, the term "modern sporting rifle" was coined by the National Shooting Sports Foundation for its survey that year as a marketing term used by the firearms industry to describe modular semi-automatic rifles including AR-15s.[16][4][17][10] Today, nearly every major firearm manufacturer produces its own generic AR-15 style rifle.[18][17] As Colt continues to own and use the AR-15 trademark for its line of AR-15 variants, other manufacturers must use their own model numbers and names to market their AR-15 style rifles for commercial sale.[19]

Under US law, when manufactured with a barrel length less than 16 inches (410 mm) and without a shoulder stock, it is legally considered a pistol as opposed to being a short-barreled rifle,[20] and is described as an AR-15 style pistol.

Modularity

While most earlier breech-loading rifles had a single receiver housing both the trigger and reloading mechanism, an innovative feature of the AR-15 was modular construction to simplify substitution of parts and avoid need for arsenal facilities for most repairs of malfunctioning military rifles.[21] A distinctive two-part receiver is used by both military and sporting AR-15 style rifles. As civilian ownership of AR-15 style rifles became sufficient to create a market for improvements, numerous manufacturers began producing one or more "improved" modules, assemblies, or parts with features not found on factory rifles, and individuals with average mechanical aptitude can often substitute these pieces for original equipment. Due to the vast assortment of aftermarket parts and accessories available, AR-15 style rifles have also been referred to as "the Swiss Army knife of rifles,"[22] "Barbie Dolls for Guys,"[23][24] or "LEGOs [sic] for adults".[25][26][27] These more or less interchangeable modules are a defining characteristic of AR-15 style rifles.[28]

A stripped lower receiver, one that is lacking the additional parts included in a completed lower receiver, is the only part of an AR-15 style rifle that needs to be transferred through a federally licensed firearms dealer under United States federal law.[29]

The lower receiver is the serial-numbered part legally defined as the firearm under United States law. However, this definition is currently questionable due to a 2019 court ruling that the AR-15 lower receiver does not match the legal definition in 27 CFR § 479.11.[30][31][32] A completed lower receiver is visually distinguished by the trigger guard ahead of the detachable pistol grip, and behind the magazine well capable of holding detachable magazines. The lower receiver holds the trigger assembly including the hammer, and is the attachment point for the buttstock. The lower receiver is attached to the upper receiver by two removable pins. Disassembly for cleaning or repair of malfunctions requires disengaging these pins from the upper receiver. Removal of the rear take-down pin allows the receiver to be opened by rotation around the forward pivot pin as a hinge.[21]

The upper receiver contains the bolt carrier assembly and is attached to the barrel assembly. Sights will be attached to the upper receiver or the barrel assembly. A handguard usually encloses the barrel and a gas-operated reloading device using burnt powder gas vented from a hole (or port) in the barrel near the forward end of the handguard. The handguard is attached to the upper receiver and may also be attached to the barrel.[21]

The initial design included a tube to vent burnt powder gas back into the bolt carrier assembly where it expands in a variable volume chamber forcing the bolt open to eject the spent cartridge case. A buffer spring in the buttstock then pushes the bolt closed picking up a new cartridge from the magazine. This direct gas impingement (DGI) system has the disadvantage of venting un-burned smokeless powder residue into the receiver where it may ultimately accumulate in quantities causing malfunctions. Some AR-15 style rifles use an alternative short-stroke gas piston design borrowed from the AR-18, where a metal rod pushes against the bolt carrier, driven by a piston located just behind the barrel gas port. This piston design keeps the rifle cleaner by not exhausting in to the receiver.[33] While both the DGI and piston systems produce semi-automatic fire, an alternative un-ported barrel assembly includes a sliding handguard connected to a rod moving the bolt by a pump action and eliminating semi-automatic fire.[34] Some AR15-style rifle models feature redesigned gas systems so the rifle is over-the-beach capable to let it fire safely as quickly as possible after being submerged in water. The initial design's construction did not take that capability in account.[35][36] The original design features a free-floating firing pin. To reduce the risk of slam-firing, some AR15-style rifle models feature a (proprietary) firing pin safety in the bolt. Such firing pin safeties can obstruct the upper to work with standard AR-15 type full height hammers in the fire control group of the lower.[37]

Most rifles eject spent cartridges from the right side of the receiver away from right handed shooters who place the butt against the right shoulder while sighting with the right eye and using a finger of the right hand to pull the trigger.[38] Right-side ejection is a disadvantage for the third of the population whose left eye is dominant,[39] and for the tenth of the population who are left handed,[40] because holding these rifles against their left shoulder for maximum accuracy causes the rifle to eject hot spent cases toward the chest, neck or face of a left handed shooter.[41] When the M16A2 was adopted by the Army in 1986, it incorporated a built-in brass deflector to prevent that happening. Most civilian-legal variants also copy that feature.[42] The modular design of AR-15 style rifles has encouraged several manufacturers to offer specialized parts including leftward ejecting upper receivers for converting right handed AR-15 style rifles for left handed use.[43][44][45]

The AR-15 is nominally chambered in .223/5.56mm NATO, but many variants have been produced in different calibers such as .22-LR, 7.62×39mm, 9×19mm Parabellum[46] and shotgun calibers.[47] Some of these firearms chambered in smaller calibers such as 9mm or .22 utilise the blowback[48] or delayed blowback[49] operating principle instead of DI/piston, as insufficient gas pressure or volume is produced by the round to cycle the action, or the simpler blowback system is sufficient and may allow removal of the rear buffer tube and spring. Some rare AR-15-style rifles are also available as bolt action firearms rendering them incapable of semi-automatic fire.[34][50][51] These are most commonly marketed in jurisdictions where ownership of semi-automatic rifles is heavily restricted such as in the United Kingdom.

Some AR-15-style rifles have features limiting use of detachable magazines to comply with state regulations.[52][53] Nearly all versions of the civilian AR-15 have a pistol grip like the military versions, and some have folding or collapsible stocks like the M4 carbine which reduce the overall length of the rifle, however AR-15 style lower receivers that accept a non-pistol-grip are available.[54]

Comparison to military versions

The semi-automatic civilian AR-15 was introduced by Colt in 1963. The primary distinction between civilian semi-automatic rifles and military assault rifles is select fire. Military models were produced with firing modes, semi-automatic fire and either fully automatic fire mode or burst fire mode, in which the rifle fires several rounds in succession when the trigger is depressed. Most components are interchangeable between semi-auto and select fire rifles including magazines, sights, upper receiver, barrels and accessories.[55][56] The military M4 carbine typically uses a 14.5-inch (37 cm) barrel. Civilian rifles commonly have 16-inch (41 cm) or longer barrels to comply with the National Firearms Act.[57]

To prevent a civilian semi-automatic AR-15 from being readily converted for use with the select fire components, several features were changed. Parts changed include the lower receiver, bolt carrier, hammer, trigger, disconnector, and safety/mode selector. The semi-automatic bolt carrier has a longer lightening slot to prevent the bolt's engagement with an automatic sear. Due to a decrease in mass, the buffer spring is heavier. On the select-fire version, the hammer has an extra spur which interacts with the additional auto-sear that holds it back until the bolt carrier group is fully in battery, when the automatic fire is selected.[58] Using a portion of the select fire parts in a semi-automatic rifle will not enable a select fire option (this requires a registered part with the ATF). Lower receivers that are select-fire are identified by a pinhole above the safety/mode selection switch.[59][60][61][62] As designed by Colt the pins supporting the semi-auto trigger and hammer in the lower receiver are larger than those used in the military rifle to prevent interchangeability between semi-automatic and select-fire components.[63]

Production and sales

The first version produced for commercial sale by Colt was the SP1 model AR-15 Sporter, in .223 Remington, with a 20-inch (51 cm) barrel and issued with five-round magazines.[14] Initial sales of the Colt AR-15 were slow, primarily due to its fixed sights and carry handle that made scopes difficult to mount and awkward to use.[64] Military development of the compact M4 carbine encouraged production of a 16-inch (41 cm) barreled civilian SP1 carbine with a collapsible buttstock beginning in 1977. These carbines have become popular for police use in confined urban spaces, and the collapsible buttstock compensates for the additional thickness of body armor. The shorter barrel reduced bullet velocity by about five percent, and bullet energy by about ten percent. The shorter barrel required moving the gas port closer to the chamber exposing the self-loading system to higher pressures and temperatures which increase stress on moving parts like the bolt lugs and extractor. Although Colt offered a heavier 20-inch barrel for improved accuracy beginning in 1986, increased barrel weight may impair ergonomic balance; so shorter barrels have dominated recent rifle production.[65]

In the 1990s, sales of AR-15 style rifles increased dramatically, partly as a result of the introduction of the flat top upper receiver (M4 variant) which allowed scopes and sighting devices to be easily mounted as well as new features such as free floating hand guards that increased accuracy.[64] While only a handful of companies were manufacturing these rifles in 1994, by the 21st century the number of AR-15 style rifles had more than doubled.[66] From 2000 to 2015, the number of manufacturers of AR-15 style variants and knock-offs increased from 29 to about 500.[67] AR-15 style rifles are now available in a wide range of configurations and calibers from a large number of manufacturers. These configurations range from standard full-sizes rifles with 20-inch (51 cm) barrels, to short carbine-length models with 16-inch (41 cm) barrels, adjustable length stocks and optical sights, to long range target models with 24-inch (61 cm) barrels, bipods and high-powered scopes.[68]

In September 2019, Colt Firearms announced it was discontinuing production of the AR-15 for the consumer market, citing "significant excess manufacturing capacity" across the industry and the company's "high-volume contracts" with military and police forces that were "absorbing all of Colt's manufacturing capacity for rifles."[69] However, in 2020 Colt resumed production of the AR-15, following a surge in demand in the United States consumer market.[70]

Estimates vary as to how many of the rifles are owned in the United States. The National Shooting Sports Foundation has estimated that approximately 5 million to 10 million AR-15 style rifles exist in the U.S. within the broader total of the 300 million firearms owned by Americans.[71]

Hunting

Many hunters prefer using AR-15 style rifles because of their versatility, accuracy, wide variety of available features, and wide variety of calibers (see below).[72] Collapsible stocks are convenient for hunters who pack their rifles into remote hunting locations or for length of pull adjustments to fit any sized hunter.[73] Construction with lightweight polymers and corrosion-resistant alloys makes these rifles preferred for hunting in moist environments with less concern about rusting or warping wood stocks. Positioning of the AR-15 safety is an improvement over traditional bolt action hunting rifles. Many states require hunters to use reduced-capacity magazines.[74] If a hunter misses with a first shot, the self-loading feature enables rapid follow-up shots against dangerous animals like feral pigs or rapidly moving animals like jackrabbits.[72] Hunters shooting larger game animals often use upper receivers and barrels adapted for larger cartridges or heavier bullets. Several states prohibit the use of .22 caliber cartridges like the .223 Remington on large game.[75][76][77]

Cartridge variations

Since the upper and lower receivers may be swapped between rifles, forensic firearm examination of bullets and spent cartridges may reveal distinguishing marks from the barrel and upper receiver group without identifying the lower receiver for which legal records may be available.[78] An individual may use several upper receiver groups with the same lower receiver. These upper receiver groups may have differing barrel lengths and sights and may fire different cartridges. A hunter with a single lower receiver might have one upper receiver with a .223 Remington barrel and telescopic sight for varmint hunting in the open country and another upper receiver with a .458 SOCOM barrel and iron sights for big-game hunting in brushy woodland. The dimensions of upper and lower receivers originally designed for the 5.56×45mm NATO cartridge impose an overall length limit and diameter limits when adapting modules for other cartridges included in this list of AR platform calibers.[79][68] The same magazine in the lower receiver group may hold differing numbers of different cartridges.[33]

Use in crime and mass shootings

Most firearm-related homicides in the United States involve handguns.[80][81][82] A 2019 Pew Research study found that 4% of US gun deaths were caused by semi-automatic rifles, a category which includes AR-15 style rifles.[83] According to a 2013 analysis by Mayors Against Illegal Guns, 14 out of 93 mass shootings involved high-capacity magazines or assault weapons.[84] Nevertheless, AR-15 style rifles have played a prominent role in many high-profile mass shootings in the United States[85] and have come to be widely characterized as the weapon of choice for perpetrators of these crimes.[86] AR-15s or similar rifles were the primary weapons used in around half of the 10 deadliest mass shootings in modern American history,[87][88] including the 2012 Sandy Hook Elementary School shooting, the 2015 San Bernardino attack,[6] the 2017 Las Vegas shooting,[89] the 2017 Sutherland Springs church shooting,[89] and the 2018 Stoneman Douglas High School shooting.[90] Gun expert Dean Hazen and mass murder researcher Pete Blair think that mass shooters' gun choices have less to do with the AR-15's specific characteristics but rather with familiarity and a copycat effect.[91][92]

Following the use of a Colt AR-15 rifle in the Port Arthur massacre, the worst single-person shooting incident in Australian history, the country enacted the National Firearms Agreement in 1996, restricting the private ownership of semi-automatic rifles. (Category D[93]).[94][95][96] As a result of the Christchurch mosque shootings with an AR-15 during Friday Prayer on 15 March 2019, the New Zealand government enacted a law to ban semi-automatic firearms, magazines, and parts that can be used to assemble prohibited firearms.[97][98] After the 2020 Nova Scotia attacks, the deadliest rampage by a single person in Canadian history,[a] Canada banned a class of rifles, including the AR-15.[100][101]
