Keymount Muzzle Brake

The Dead Air Armament Keymount Muzzle Brake is available now from LM Ironwerks, a licensed FFL/SOT dealer in Louisville, Kentucky.

From the engineering minds of Todd Magee and Mike Pappas, the Keymount Muzzle Brake is your gateway to silence. Use the Keymount brake to quickly attach any KeyMo’d equipped silencer to your favorite rifle. 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 traditional muzzle brakes. Available for standard 7.62x51mm and 5.56×45 threaded barrels

NOTE: DA103, DA104, DA106 do not have top port holes.
