These are compatible with Plan B type bipods. Always use an alignment rod to ensure the entire system is correctly set up. Ensure all surfaces are clean and the muzzle device is properly torqued and secured with Rockset to the barrel. Be aware that using this on a Q can voids your warranty. Torque the muzzle device to approximately 15 ft-lb - 25 ft-lb, ensuring it is square against the shoulder. When attaching the silencer to the muzzle device, make sure the threads and tapers are clean. Torque the suppressor to 10 ft-lb and verify alignment.
