The Kak Industry Plan B Universal Muzzle Device in 5/8x24 offers a reliable, repeatable lockup with a proper seal between the muzzle device and Plan B suppressor adapter, ensuring consistent performance when used with Plan B suppressor mounts for 7.62x51mm NATO rifles. This muzzle device features a precise taper followed by threads, delivering repeatable alignment and a secure interface, while its 1-inch overall length and .895-inch outside diameter preserve barrel harmonics and weight balance for practical field use. Crafted from 17-4 stainless steel with a durable nitride finish, it weighs 1.6 oz and is fully precision machined in-house at Kak Industry, with milled flats for easy installation and a 13/16-inch drive engagement. Each unit is engraved with its respective thread pitch for quick identification, and the bore is universal, compatible with a range of standard suppressors. For best results, Rocksett is recommended for installation and torquing to 20-25 ft-lbs to ensure a solid, heat-resistant seal. Warranty considerations from some suppressor manufacturers may apply if non-brand muzzle devices are used with their hosts, so pairing with Plan B components optimizes compatibility and reliability.
