Your Device For Great Recoil Management & Muzzle Rise Control

The Dead Air Armament Key Mount Muzzle Brake is designed to fit the Sandman’s series of suppressors. It features compensating ports drilled into the top of the brake that offers great recoil management and effectively reduces muzzle rise.

The Key Mount Muzzle Brake reduces the length of recoil so that repeating shot energy cannot overlap and knock the shooter off target. Full auto fire is also possible with massively reduced recoil and muzzle climb, meaning that all shots fall on target.

Your Gateway To Silence

The Keymount Muzzle Brake is your gateway to silence and you can quickly attach your Sandman-L or Sandman-S to your rifle for an uncompromised and quiet operation.  If you’re not quite ready to turn up the silence, you can still employ the finest brake on the market and experience a flatter shooting rifle with minimal concussion compared to any traditional muzzle brakes.
