Product Details
JMAC CUSTOMS 360 HEAVY DUTY MUZZLE BRAKE 1/2-28, X37 FACEMOUNT

The RRD-360HD is designed specifically with short barrels and high pressures in mind! Due to excess pressures and gasses associated with rifle calibers in short-barreled firearms, a barrel length restriction was put in place for many of our popular devices. To remedy this, we've taken our 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 our 360 devices, now with a Heavier Duty design for short-barreled firearms! 

The X37 Series Muzzle Brakes combine our effective RRD muzzle brake design and a direct thread mount for several popular suppressors as well as our BDS-37 and BDS-37-EXT blast shield! This allows you to leave the muzzle device installed and simply thread the suppressor over! Reduces weight, length, and cost compared to QD systems. Direct thread is also the preferred mounting method for accuracy!

The 360-28F will work on any barrel with 1/2-28 threads that extends a minimum of 1" beyond the handguard/gas block/front sight with a diameter less-than 0.7". Below is a list of firearms we have found to be compatible with the 360-28F. Regardless of your firearm, always measure your barrel to ensure your firearm is compatible with the 360-28F before purchase.

AR-15 - Must have "government profile barrel" or barrel with diameter behind the threads of <0.7".
