The KAK Industry Plan B Krink is a face-mount muzzle device threaded M26x1.5 left-hand, machined from 17-4 stainless steel with a nitride finish.
Plan B devices use a taper followed by threads, which gives repeatable lockup and a proper seal between the muzzle device and a Plan B suppressor hub. KAK recommends its own hub mount because of the device design, Rocksett for installation and 20-25 ft-lbs of torque. A multi wrench and timing shims are included. Some suppressor makers will not honor warranty claims if another brand of muzzle device is used.
