Our AR15/M16 Bolt provides superior function and cleaning characteristics. The DLC finish allows for an extremely hard surface, as well as excellent lubricity.
The bolt is machined from SAE 4140ph high-grade steel – even the extractor is machined from billet! This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure, and providing a long service life. Bolt is shot peened and MPI inspected. Includes: extractor, extractor spring, extractor insert & O-ring, ejector cartridge and spring, and three gas rings.
