JMAC CUSTOMS LLC RECOIL REDUCTION DEVICE 2 PORT X37 COMPENSATOR 45 CAL 5/8-24

The X37 Series Muzzle Brakes combine JMac’s effective RRD muzzle brake design and a direct thread mount for several popular suppressors as well as their 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!

• Not intended or recommended for barrels shorter than 10.5” when used with rifle calibers

When testing these devices using rifle calibers, JMac found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.

JMac Customs is NOT responsible for improper installation of this muzzle device or any damage to the suppressor using this device. We recommend this be professionally installed and checked to ensure alignment.

JMac Customs recommends that all suppressor mounts be installed and checked for alignment by a certified professional.
