Dead Air 7.62mm KeyMount Muzzle Brake | 1/2x28 Thread

The 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. Our sealed taper design is forward of the Keymo locking channels, allowing the suppressor to be easily removed without carbon-locking onto the mount. NOTE: The DA101 and DA102 come with a pre-drilled hole for pin & weld at the 6 O'clock position. The DA103, DA104, and DA106 do not have a pin/weld hole and do not have the three port holes on the top wrench flat. 

Keymo Brakes come with an included shim kit for timing your muzzle device.
