The X37 Series Muzzle Brakes from JMAC CUSTOMS LLC. Recoil reduction device with a direct thread mount for several popular suppressors as well as our BDS-37 and BDS-37-EXT blast shields. 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.
