Plan B muzzle devices feature a taper followed by threads resulting in repeatable lockup and a proper seal between the muzzle device and suppressor adapter
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. Enjoy. The nitride finish does lead to a tighter seal, with that said, it is extremely important to torque and rockset your muzzle device to the barrel properly.
