Manticore Arms NightBrake Muzzle Compensator - 1/2x28
With the same excellent performance as the original NightBrake, the new 1/2x28 threaded can be installed on any AR-15, SIG 556, or other commonly threaded 1/2x28 barrel by using the integral wrench flats and the included crush washer.
The NightBrake is specifically designed to provide recoil reduction and virtually eliminate muzzle rise. A total of eighteen ports distributed around the upper 270 degrees of the device help stabilize and reduce exiting gas pressure. There are no ports facing directly upwards to allow for an uninterrupted sight picture when firing, and the lower 90 degree arc has no ports to prevent a dust signature when fired.
The NightBrake 1/2x28 tpi will clear any projectile up to .30 caliber (0.311") safely and is discretely marked "MA" on the underside to denote it as a USA made 922r compliance part.
Weighing only 2 ounces and only 1.875" in length, it is machined from 8620 steel bar stock, heat treated, and finished in a deep black oxide.
