The Dead Air KeyMo Muzzle Brake is used 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 use this brake to experience a flatter shooting rifle with minimal concussion. When it comes to removal, this brake allow the suppressor to be easily removed without carbon-locking onto the mount.

Please note: The 3/4X24, M18X1, and M18X1.5 thread pitches do not come with timing shims and do not have top port holes.
