JMAC Customs RRD-2C 30S X37 Universal 1.375" Suppressor Mount


In order to use this device with a suppressor, it must be installed by a professional - to ensure it is properly mounted and aligned. Do NOT shoot without checking alignment with bore rods. JMac Customs is not responsible for any damage to the suppressor, or any injury resulting from improper installation. Some firearms are NOT suitable suppressor hosts, just because you can thread this muzzle device on, does NOT mean it is safe to use. If you only want to use the 2C X37 with the BDS-37 Blast Diversion Shield, you can install it using a crush washer. 


The X series muzzle brakes combine their effective RRD muzzle brakes and a direct thread mount for several popular suppressors as well as their BDS-37 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 X37 has 1.375”-24 threads on the outside and is available in multiple barrel thread pitches.
