The Dead Air KeyMo Muzzle Brake is your gateway to silence. When you're ready for peace and quiet use the KeyMo brake to quickly attach your Sandman Series or KeyMo equipped suppressor 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. When it comes to removal, the suppressor can be easily removed without carbon-locking onto the mount.
