Product Description
KAK Industry K-SPEC AR-15 bolt is a complete assembled bolt designed to improve ejection reliability and consistency for 5.56 NATO and .300 Blackout direct-impingement rifles. The K-SPEC dual ejector system uses standard Mil-Spec ejectors and springs (no proprietary parts), with ejector holes centered on the lugs to help maintain bolt strength. Built from 9310 steel and finished in machine gun hard chrome for durability and backwards compatibility with standard Mil-Spec AR-15 bolt carrier group components.
