Dead Air KeyMount Muzzle Brake | 1/2-28 | DA101

The Dead Air KeyMount (KeyMo) Muzzle Brake DA101 provides a KeyMo-compatible mounting interface for KeyMo-equipped suppressors and serves as a functional muzzle brake when a suppressor is not installed. It is finished in black and constructed of steel. The product uses a sealed taper design intended to reduce the chance of carbon lock when a suppressor is removed.

Typical applications include range and precision/practical shooting where rapid attachment/removal of a KeyMo-compatible suppressor is desirable, and use as a muzzle device to reduce felt recoil and muzzle rise during follow-up shots.
