KAK Industry K-SPEC Enhanced Features The KAK Industry K-SPEC Enhanced bolt carrier group is built around a C158 steel bolt with a dual ejector configuration giving the rifle more consistent extraction and ejection cycle after cycle. Downward-angled gas ports direct carbon and gas away from critical surfaces reducing fouling buildup inside the carrier key and bolt area. Slotted angled carrier rail cuts further manage debris helping the carrier stay smoother and cleaner during extended shooting sessions. The full auto profile carrier matches mil-spec dimensions keeping it compatible with a wide range of AR-15 upper receivers and bolt carrier group accessories. Finished in Phosphate over a chrome lined interior the K-SPEC Enhanced BCG is built to resist corrosion and wear while remaining easy to field strip and clean after a day at the range. That combination of finishes is particularly suited to suppressed shooting where carbon buildup and heat are more pronounced. Chambered for both 5.56 NATO and .300 AAC Blackout this carrier group covers two of the most popular AR-15 chamberings in one part. The KAK Industry K-SPEC Enhanced Bolt Carrier Group is a dependable upgrade for shooters building or maintaining a rifle meant to run reliably in any condition.
