CheyTac Intervention

Intervention with ammunition

The CheyTac M200 Intervention is an American bolt action sniper rifle manufactured by Randy Kobzeff for long range soft target interdiction. It is fed by a detachable single stack magazine, which holds 6 rounds. It fires .408 CheyTac or .375 CheyTac ammunition. CheyTac papers state that the entire system is capable of delivering sub-MOA accuracy at ranges of up to 2,500 yards (2,300 m), one of the longest ranges of all modern-day sniper rifles. It is based on the EDM Arms Windrunner.

Long Range Rifle SystemEdit

The Intervention M-200 rifle is part of CheyTac's "Long Range Rifle System", which includes CheyTac tactical ballistic computer (commercial PDA with CheyTac ballistic software), Kestrel 4000 Pocket Weather Tracker that finds wind/temperature/humidity/atmospheric pressure and Vector IV laser rangefinder linked to the PDA, Nightforce NXS 5.5-22x56 telescopic sight and a muzzle brake and suppressor.



The Intervention holds the world record for best group at a distance, landing 3 bullets within 16⅝ inches (42 cm) at 2,321 yards (2,122 m) near Arco in Idaho.

On the TV show Future Weapons episode "Massive Attack" the host Richard Machowicz, a former United States Navy SEAL, made 3 out of 6 shots hit a human sized sheet of metal at a distance of 2,530 yards (2,313 m) at Arco Pass in Idaho.


CheyTac asserts in its Information Paper of 13 November 2006 that "the CheyTac LRRS is a solid anti-personnel system to 2,000 yards (1,830 m). The primary intent of the .408 is as an extreme range anti-personnel system. Groups of 7–9 inches (18–23 cm) at 1,000 yards (914 m), 10 inches (25 cm) at 1500 yards (1372 m) and 15 inches (38) cm at 2,000 yards (1,829 m) have been consistently obtained.

Groups of 19 inches (48 cm) at 2,100 yards (1,920 m) and 29 inches (74 cm) at 2,400 yards (2,195 m) have also been obtained. All groups that are up to 3,000 yards (2,743 m) are less than 1 minute of angle for vertical dispersion.


The CheyTac Intervention comes in several variants:

  • M-200 (29 in (737 mm) barrel length)
  • M-200 Carbine
  • M-310 (Single shot and repeater sub-variants all with 29 in (737 mm) barrel length)
  • M-325 (Single shot, repeater and tactical sub-variants all with 28 in (711 mm) barrel length)

The main capability differences between the different versions are governed by barrel length which determines the obtainable muzzle velocity. Higher muzzle velocity will extend the effective range of a rifle, everything else being equal. Also, the M-200 and the M-200 Carbine comes with a detachable box magazine and a telescopic stock, whilst the other variants are built on a glass-fiber fixed McMillan stock.
