KAK Industry K-SPEC Enhanced AR-15 Bolt Dual Ejector 9310 Steel Phosphate Finish 303-0502-011

Product Description

The KAK Industry K-SPEC Enhanced AR-15 bolt is designed to improve ejection consistency and reliability in 5.56 NATO / 300 Blackout builds. Its 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. This complete assembled bolt is made from durable 9310 steel and finished in a protective phosphate coating, and it remains backwards compatible with standard Mil-Spec bolt carrier group (BCG) components for easy integration into AR-15 style direct impingement systems.
