KAK Industry Plan B Universal Muzzle Device 11/16-24

Plan B muzzle devices are the mounting half of a suppressor setup rather than a brake or a flash hider. The body carries a taper followed by threads, so a Plan B suppressor hub seats on the taper for repeatable lockup and seals against gas at the shoulder. The bore is universal, so one part covers a spread of calibers.

Install it with Rocksett and torque it to 20 to 25 ft-lbs. The milled flats take a 13/16" wrench and the thread pitch is engraved on the body, so you are not guessing a year from now which one is on which barrel. Worth noting: some suppressor makers will not honor a warranty claim if another brand of muzzle device is run under their can.
