These fit the plan B type mounts. Always use an alignment rod to ensure that the entire system is set up correctly. Make sure all surfaces are cleaned and the muzzle device has been torqued and Rockset to the barrel. Use on a Q can voids your warranty, be warned.
Torque the muzzle device to approximately 30 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.

This flash hider was the first one I have personally shot at night on a 10.5″ 300blk. It produced a small dark orange flame about 1.5″ wide and 2.5″ long with Frontier 125gr supers. I filmed it and will upload to youtube today. Paired with a suppressor and flash cap it made a tiny flash smaller than a bic lighter flame on the first shot (burning all the oxygen in the can) then made ZERO flash after the initial shot. Per usual it aligned my can perfectly and looks sick.
