Dead Air KeyMo Muzzle Brake | 11/16-24 | DA163

The Dead Air KeyMo Muzzle Brake is a KeyMo-compatible quick-detach muzzle device designed to mate with KeyMo-equipped silencers while providing effective muzzle braking. It is produced from heat-treated alloy steel and finished in a black nitride for corrosion resistance and durability. The mount uses a muzzle-seating design intended to reduce the need for shims on many barrels and to minimize carbon locking for easier suppressor removal. Typical applications include range and precision practice where improved recoil control and rapid suppressor attachment/detachment are desired.
