SPB MUZZLE BRAKES fit Plan B type mounts. Use an alignment rod to ensure that the entire system is set up correctly. Clean all surfaces and torque the muzzle device and Rockset to the barrel. Using on a Q can void warranty; be warned.
Torque the muzzle device to approximately 15–25 ft-lbs. Make sure the muzzle device is square against the shoulder. When setting the silencer on the muzzle device, ensure that the threads and tapers are clean. Torque the suppressor to 10 ft-lbs. Ensure alignment. The nitride finish can lead to a tighter seal, with that said, it is extremely important to torque and rockset your muzzle device to the barrel properly.
