CheyTac Intervention

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.[1] 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.[2]

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.[2]

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.[2]

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.[3][2]

Vector laser range finder binoculars.

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.[4]

• 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.[3] 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.[3] 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.[3][5]
• 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.[3]

The Intervention holds the world record for best group at a distance, landing 3 bullets within 16.625 in (42.23 cm) at 2,321 yd (2,122 m) near Arco in Idaho.

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.[6][7]

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.[3]

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.[9]

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.[9]

The CheyTac M300 Intervention (Composite) is a civilian/sporting variant of the M300 Intervention (Carbon Fiber). It is well suited under challenging terrains due to its lightweight build. The platform has been proven in combat and long distance big game hunting, and can be maintained easily making it ideal for an extended amount of time in the field.[10]

The M300 Intervention (Composite) 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 19 lb (8.6 kg). It features a Picatinny rail on the top of its receiver for mounting various optics/scopes and on the bottom portion of the front end of the handguard for optional bipod mounting, 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, an adjustable buttstock that has an adjustable cheek weld, V-Block and an optional monopod, an adjustable pistol grip, an adjustable match trigger and flush cups for weapon sling mounting.[10]
