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, Sandman-S, Sandman-K, or KeyMo equipped Nomad-30 or Primal 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.
