The CheyTac Intervention is an American bolt-action sniper rifle manufactured by CheyTac LLC, which can also be classified as an anti-materiel rifle. It is fed by a 7-round detachable single-stack magazine (an optional 5-round magazine is also available). It is specifically chambered in either .408 Chey Tac or .375 Chey Tac ammunition. CheyTac LLC states that the system is capable of delivering sub-MOA accuracy at ranges of up to 2,500 yd (2,286 m), one of the longest ranges of all modern-day sniper rifles. It is based on the EDM Arms Windrunner. With the passing of Bill Ritchie, the rifles are being serviced by Vigilance Rifles, Inc, run by Bill Ritchie's son.

The CheyTac system consists of three major components:
- .408/.375 CheyTac ammunition
- CheyTac "XTreme Long Distance™" Rifle
- CheyTac Advanced Ballistic Computer
The CheyTac M200 Intervention is a manually operated, rotating bolt sniper rifle. It features a Picatinny rail on the top of its receiver for mounting various optical sights.
The M200 Intervention is chambered in either the .408 CheyTac or .375 CheyTac cartridge. CheyTac specially developed the .408 CheyTac/.375 CheyTac cartridge for long-range use. The cartridge is optimized for accuracy by a balance of the rotational and linear drag, which reduces yaw and precession, and keeps the tip of the projectile pointed along the trajectory.
The M200 Intervention is fed through a detachable 7 round box magazine, an optional 5 round box magazine is also available. Alternatively cartridges can be loaded singly directly into the chamber.
The M200 Intervention uses a free floating heavy-fluted barrel, which can be quickly removed for replacement or storage and transportation, and the shroud at the rear serves as a mount for an integral folding bipod and a carrying handle.
To achieve balanced flight the rifling twist rate for the .408 CheyTac chambering was chosen at 330.2 mm (1:13 in), with eight 0.4080 in diameter grooves, 0.4010 in diameter bore and a 0.050" land width, square cut, with no taper. The later .375 CheyTac round, developed from the .408 CheyTac, uses a 292 mm (1:11.5 in) rifling twist rate.
The M200 Intervention features the McArthur PGRS-1 muzzle brake, which can be used to reduce recoil. It was designed by a gunsmith and firearm inventor, Bruce McArthur, owner of The Flint & Frizzen Gun Shop in Clarkston, Michigan. The muzzle brake is also removable and can be replaced by an OPSINC suppressor.
The M200 Intervention has a collapsible and retractable buttstock that is adjustable for length of pull for ease storage and transportation. The buttstock also contains an integral rear monopod, which is hinged, and can be folded up when not in use.
Day and low light optical sights
There are two different day optical sights available for the M200 Intervention. The standard optical sight is the Nightforce NXS 5.5-22x56 variable magnification telescopic sight with a 56 mm objective. The alternative optical sight is the US Optics SN-9. The night vision system is the AN/PVS-14 GEN III Pinnacle monocular, which attaches to the day optic using the Monoloc device. An AN/PEQ-2 infrared laser provides additional lighting in low-light conditions. The device is attached to a titanium strut.
The M200 Intervention comes with a portable advanced ballistic computer, laser rangefinder binoculars and meteorological and environmental sensor package. All these components, together with the sniper rifle, are part of the CheyTac Long Range Sniper System (LRRS) and are linked to the ballistic computer. It provides all necessary data and calculations for accurate long range firing.
- Advanced Ballistic Computer - The CheyTac Advanced Ballistic Computer (ABC) System software package uses tabulated bullet flight data derived from high speed Doppler radar test sessions, and mathematical models to predict ballistic trajectory. It runs on Windows Mobile 2003 and receives input from the Kestrel handheld weather station and Vector IV laser rangefinder binoculars. However, much like other ballistic prediction software, when rounds are used for which no Doppler Radar-established bullet flight data is known, the ABC System relies solely on mathematical ballistic models like all other ballistic prediction computer programs. Printed data tables are available for manual use. Without computer support the effectiveness of some long-range shooters could be severely reduced, since they may rely heavily on computer support to obtain accurate ballistic estimates.
- Meteorological and environmental sensor package - The KESTREL 4000 (or, 4500 NV) meteorological and environmental sensor package measures the wind speed, air temperature, air pressure, relative humidity, wind chill, and dew point. The KESTREL 4500 NV model is compatible with night vision devices.
- Laser rangefinder - The Vector IV mil spec laser rangefinder measures distances up to 6,000 m (6,561.7 yd), and houses a digital compass and class 1 eye safe filters.
On the Discovery Channel TV show Future Weapons April 9, 2007, episode "Massive Attack" the host Richard Machowicz, a former United States Navy SEAL, made 3 out of 6 shots, hitting a human-sized sheet of metal at a distance of 2,530 yd (2,313 m) at Arco Pass in Idaho.
CheyTac states that "the CheyTac LRRS is a solid anti-personnel system to 2,000 yd (1,829 m)." The primary intent of the .408 is as an extreme range anti-personnel system. Groups of 7 to 9 in (18 to 23 cm) at 1,000 yd (914 m), 10 in (25 cm) at 1,500 yd (1,372 m) and 15 in (38 cm) at 2,000 yd (1,829 m) have been consistently obtained.
Groups of 19 in (48 cm) at 2,100 yd (1,920 m) and 29 in (74 cm) at 2,400 yd (2,200 m) have also been obtained. All groups that are up to 3,000 yd (2,743 m) are less than 1 minute of angle for vertical dispersion.
The CheyTac Intervention comes in several variants:
- M200 (29 in (737 mm) barrel length)
- M200 Carbine (Now out of production)
- M200 CIV (Civilian Variant)
- M200 RK
- M310 (Single shot and repeater sub-variants all with 29 in (737 mm) barrel length)
- M310 R (Repeater)
- M325 (Single shot, repeater and tactical sub-variants all with 28 in (711 mm) barrel length)
The main capability differences between the different variants are governed by barrel length which determines the obtainable muzzle velocity. Higher muzzle velocity extends the effective range of a rifle, everything else being equal. The M200 and the M200 Carbine are and were limited to official customers like military forces and come with a detachable box magazine and a telescopic stock, whilst the current (2013) other variants have a glass-fiber fixed McMillan A5 stock and are available for the general public.
CheyTac M300 Intervention (Carbon Fiber)
The CheyTac M300 Intervention (Carbon Fiber) is a modern rendition of the M200 Intervention. CheyTac utilized lightweight materials such as aluminum and carbon fiber to achieve a lightweight portable sniper rifle that doesn't compromise on strength, accuracy, or agility.
The M300 Intervention (Carbon Fiber) can be chambered in either .408 CheyTac or .375 CheyTac cartridge and uses a 7-round detachable box magazine. It has an effective range of 2,500 yd (2,286 m), and a weight of 21 lb (9.5 kg). It features all of the standard features of the M200 Intervention and also features a full-length Picatinny rails at 3, 6, 9 and 12 o’clock positions for mounting various accessories, such as accuracy enhancements, a 29 in (740 mm) fluted barrel (custom lengths are also available), a barrel twist rate of 1:13.25" twist for the .408 CheyTac cartridge and 1:11.25" twist for .375 CheyTac cartridge, a detachable muzzle brake, a fully adjustable folding buttstock that has an adjustable cheek weld, a recoil pad and an optional monopod, an adjustable pistol grip, an adjustable match trigger and flush cups for weapon sling mounting.

In popular culture
The CheyTac Intervention is featured in the highly successful 2009 video game Call of Duty: Modern Warfare 2 where it became a fan favourite because of it being the only bolt-action rifle available in the game's multiplayer, which made it harder to use effectively than most other weapons, but in the hands of a skilled player it could be a force to be reckoned with because of its ability to kill opponents with one bullet to the chest. Thanks to this ability the gun would be used to pull of trickshots. One notable kind of trickshot is the "360 noscope," whereby the player jumps off of something, turns 360 degrees, and then kills an opponent without using the scope. This, along with its very recognisable sound, made it one of the most iconic weapons in video game history.

- Doing MOA capability testing is expensive. This is done by shooting 100 shots, no less than 2 minutes between each shot, correcting for conditions on each shot at 90% of the gun's supersonic range. You count the number of shots within an x MOA diameter. 80% of those shots in an x MOA arc within 90% of supersonic capability gives a REAL MOA value capability for a military grade long range rifle. If 80% of those shots fall within 0.9 MOA, then that is the gun's capability. If humans are shooting the guns, then you should use at least 5 shooters and average the values. Of course, a gun's individual capability should be tested at 200 yd (183 m) to determine if the gun can hold a real group or not. We did this with the .408 in 2001 and 2002. Gives honest numbers, but costs a lot. (statement by Mr. Dean Michaelis, former co-owner and test shooter of CheyTac LLC)
