The CheyTac Intervention is an American-made bolt action heavy sniper rifle designed by CheyTac LLC. for long range soft target interdiction (i.e., anti-personnel/sniper). The CheyTac Intervention rifle is fed using a detachable single stack magazine, which holds 5 or 7 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 2500 yards (2286 m), one of the longest ranges of all modern-day sniper rifles. It is based on the EDM Arms Windrunner.
