The CheyTac Intervention, also known as the CheyTac M200, is an American bolt-action sniper rifle manufactured by CheyTac USA, which can also be classified as an anti-materiel rifle. It is fed by a seven-round detachable single-stack magazine (an optional five-round magazine is also available). It is specifically chambered in either .408 Chey Tac or .375 Chey Tac ammunition. CheyTac Inc. states that the system is capable of delivering sub-MOA accuracy at ranges of up to . It is based on the EDM Arms Windrunner.
The CheyTac M200 Intervention has an overall length of 56 inches and can be shortened to 46.75 inches with the stock collapsed. Its weight is 31 lbs without an optic, and it has a 29-inch barrel. The rifle is designed for long-range precision, with an effective range of over 2,500 yards. It is a well-known weapon for its extreme precision, despite being available for civilian use. This has come under intense scrutiny in recent years.
Design details
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.
Cartridge
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 individually directly into the chamber.
Barrel
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.
Attachable muzzle devices
The M200 Intervention features the McArthur PGRS-1 muzzle brake, which can be used to reduce recoil. The muzzle brake is also removable and can be replaced by an OPSINC suppressor.
- Laser rangefinder – The Vector IV mil spec laser rangefinder measures distances up to , and houses a digital compass and class 1 eye safe filters.
Groups of at and at have also been obtained. All groups that are up to are less than 1 minute of angle for vertical dispersion.
- M200 (29 in (737 mm) barrel length)
- M200 Carbine
- M200 CIV (Civilian variant, no longer produced)
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 CIV version was a marginally de-rated Mil Spec M200 with a 500 yard shorter effective range, this version was soon discontinued, and the 29 inch fully accurized version is the only version available for sale.
