KAK Industry K-SPEC Enhanced AR Bolt – 5.56/.300 BLK

The KAK Industry K-SPEC Enhanced AR Bolt is a direct replacement bolt for AR-15 rifles chambered in 5.56 NATO or .300 Blackout. Designed for shooters who need a reliable spare or want to upgrade from a worn factory bolt, this component maintains headspace and function with standard AR-15 bolt carrier groups. The phosphate finish provides corrosion resistance for extended service life.

Machined from mil-spec steel with a phosphate coating, this bolt features properly staked extractor components and a correctly profiled cam pin slot. Installation requires headspace verification by a qualified gunsmith—this is not a drop-in part. Shooters should always verify headspace when replacing bolts to ensure safe operation.
