The KAK K-SPEC Enhanced 7.62x39 bolt carrier group is built for AR-15 pattern rifles chambered in 7.62x39, suppressed or not. The carrier is cut to the M16 full-auto profile with angled sand-cut rails that move fouling and debris away from contact surfaces, and its gas relief ports vent downward through the magazine well instead of toward the shooter's face. A dual-ejector bolt uses standard mil-spec ejectors and springs for consistent ejection. The carrier is 8620 steel, chrome lined with an NP3 finish; the bolt is MPI-tested 9310 steel with NP3; the firing pin is chrome-plated 8740 steel; and the 4130 gas key is NP3 finished, secured with T25 Torx screws and hydraulically staked. It is machined and assembled in house by KAK Industry in Missouri.
