KAK Industry Plan B AK74 Features The KAK Industry Plan B AK74 muzzle device is machined from 17-4 stainless steel for durability under the heat and pressure generated at the muzzle of a 7.62x39 AK pattern rifle. Its design uses a taper followed by threads a combination that produces repeatable lockup and a reliable seal when mating with a Plan B compatible suppressor hub. This design philosophy helps maintain a consistent point of impact shift between suppressed and unsuppressed fire a detail serious AK shooters value. The M26x1.5 left-hand thread pitch matches common AK pattern barrel threading allowing straightforward installation on compatible rifles. Finished in a black nitride coating this muzzle device resists corrosion and wear while standing up to sustained firing without degrading. A multi wrench is included to aid installation and KAK Industry recommends using Rocksett along with 20 to 25 ft-lbs of torque to ensure the device stays properly seated. Measuring 2.55 inches overall with a protrusion of 1.55 inches into the blast chamber the device is compact enough to avoid excessive added length to the muzzle. AK platform owners running the Plan B suppressor system will find this KAK Industry muzzle device available for sale at GrabAGun.
