Available for standard 7.62x51mm (308 Winchester) and 5.56--45 threaded barrels, the Keymount Muzzle Brake is your gateway to silence. When you're ready for peace and quiet use the Keymount brake to quickly attach your Sandman-L or Sandman-S to your 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.
