JMAC 360 KeyMount HD Muzzle Brake

The RRD-360HD is designed specifically with short barrels and high pressures in mind! Due to excess pressures/gasses associated with rifle calibers in short-barreled firearms, a barrel length restriction was put in place for many of JMAC’s popular devices. To remedy this, they’ve taken their 360 design and reinforced the device by adding additional material where it's needed and removing material in some areas to cut down on size, and weight. You get the same amazing performance out of the 360 devices, now with a Heavier Duty design for short-barreled firearms!
