The JMac Customs RRD-2C 26F X37 muzzle brake has a barrel thread pitch of M26-1LH and a external thread pitch of 1.375-24.
The X series muzzle brakes combine JMacs effective RRD muzzle brakes and a direct thread mount for several popular suppressors as well as our 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.
The 14-1lh, 24-1.5 and 26-1LH use the same facemount technology that the DeadAir Wolverine uses to help with thread issues.
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.
