CheyTac Intervention

Lore & Background

The CheyTac M200 Intervention is based on the EDM Arms Windrunner. It is a manually operated, rotating bolt sniper rifle featuring a Picatinny rail on top of its receiver for mounting optical sights. The rifle uses a free-floating heavy-fluted barrel that can be quickly removed for replacement or storage. The shroud at the rear serves as a mount for an integral folding bipod and a carrying handle. The M200 features the McArthur PGRS-1 muzzle brake, which can be removed and replaced by an OPSINC suppressor. The collapsible and retractable buttstock is adjustable for length of pull and contains an integral rear monopod that folds up when not in use.

The CheyTac system consists of three major components: the .408/.375 CheyTac ammunition, the CheyTac "XTreme Long Distance™" Rifle, and the CheyTac Advanced Ballistic Computer. The cartridge was specially developed for long-range use, optimized for accuracy by balancing rotational and linear drag to reduce yaw and precession. The rifle is fed through a detachable 7-round box magazine, with an optional 5-round magazine, or cartridges can be loaded individually directly into the chamber.

Variants originally manufactured include the M200 (29-inch barrel), M200 Carbine, and M200 CIV (civilian variant, no longer produced). The M200 CIV was a marginally de-rated Mil Spec M200 with a 500-yard shorter effective range, soon discontinued. The 29-inch fully accurized version is the only version available for sale. Users include the 601st Special Forces Group, GROM operatives, and Maroon Berets operatives.

Reader's Guide

The CheyTac Intervention is notable as a complete long-range sniper system, integrating the rifle with an advanced ballistic computer, laser rangefinder binoculars, and a meteorological sensor package. The CheyTac Advanced Ballistic Computer (ABC) runs on Windows Mobile 2003 and receives input from the Kestrel handheld weather station and Vector IV laser rangefinder binoculars, using tabulated bullet flight data from Doppler radar test sessions and mathematical models to predict ballistic trajectory. The KESTREL 4000 or 4500 NV sensor package measures wind speed, air temperature, air pressure, relative humidity, wind chill, and dew point. The Vector IV laser rangefinder measures distances up to 6,000 m and houses a digital compass. CheyTac states the system is a solid anti-personnel system to 2,000 yards, with consistent groups of 7 to 9 inches at 1,000 yards, 10 inches at 1,500 yards, and 15 inches at 2,000 yards. Groups of 19 inches at 2,100 yards and 29 inches at 2,400 yards have also been obtained, with all groups up to 3,000 yards less than 1 minute of angle for vertical dispersion. The rifle's availability for civilian use has drawn intense scrutiny.
