The Dead Air 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™, Sandman-S™, or Sandman-K™ 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.

Note from Phillip: I've measured the overall length of these muzzle brakes, and they're long enough to permanently attach to most 13.7" barrels to reach legal 16" length! If you're looking for an excellent muzzle device for your 13.7" barreled build that is also a suppressor mount, we cannot recommend this Dead Air Muzzle Device enough. Click here for more muzzle devices that will bring a 13.7" barrel to legal length after being permanently attached.
