The CheyTac Intervention is an American bolt-action sniper rifle manufactured by CheyTac LLC, which can also be classified as an anti-material rifle. It is powered by a removable 7-round magazine (an optional 5-round magazine is also available). In particular, it is contained in CheyTac .408 or CheyTac .375 ammunition. CheyTac INC claims the system can provide sub-MOA accuracy over a range of up to 2,500 yards (2,286 m), one of the longest ranges of modern sniper rifles. It is based on EDM Arms Windrunner.
