Enhanced NLX556 DLC Bolt

Enhanced NLX556 DLC Bolt- Upgrade your rifle's current Bolt Carrier Group with a premium Enhanced NLX556 DLC bolt from Next Level Armament. Born from our NLX556 DLC Bolt Carrier Group, our AR15/M16 Bolt provides superior function and cleaning characteristics. The DLC finish allows for an extremely hard, easy to clean, durable surface, while providing excellent lubricity. We machine each bolt from SAE 4140ph high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure, and providing a long service life. By machining each extractor from the same steel, we created durability over stamped or cast parts found in other bolts. Each Bolt is shot peened and MPI inspected. Compatible in AR15 BCGs with .223, 5.56, .350 Legend, and 300 Blackout.The assembled bolt includes:bolt - DLC finishextractor - DLC finishextractor springextractor insert & O-ringextractor pinejector cartridge and springejector pinthree gas rings
