Product DescriptionThe KAK Industry Plan B AK74 muzzle device is engineered with a precision taper followed by threads to deliver repeatable lockup and a proper gas seal when used with Plan B suppressor adapters. Built from rugged 17-4 stainless steel, it fits AK-pattern barrels with M26x1.5 left-hand threads and supports both 5.56 and 7.62x39 bores.
