The Nightbrake provides both muzzle rise reduction and recoil reduction all in one. A total of 18 ports distributed on the up half of the muzzle device help stabilize and reduce exiting gas pressure while the lack of ports on the underside prevent dust signature. The Nightbrake is threaded 5/8 x 24 tpi and will clear any projectile up to 0.311 caliber or 7.62 mm, and is marked "MA" to denote it as a USA made 922r compliant part. A crush washer is included with the muzzle device.
