The Dead Air Armament KeyMo 46 Muzzle Brake is designed for big-bore calibers, featuring efficient muzzle braking on calibers up to .458, while offering a faster and rock-solid attachment method. For effective mounting on rifle barrels with little or no shoulder, the KeyMo 46 features a muzzle-seating design that eliminates the requirement for shims. The KeyMo 46's muzzle brake ports are designed to efficiently distribute gas and pressure inside your Dead Air silencer for superior performance and longer service life. The suppressor can be easily removed without carbon-locking onto the mount. The KeyMo 46 is compatible with all Dead Air KeyMo adapter-equipped silencers.
