Our Nitride AR-15 Bolt is precision machined by a US government ordinance and aerospace contractor with decades of experience. This assebled 5.56 bolt is engineered to take a beating and triple quality checked, you can be sure you are getting the best quality for the best price with this complete bolt.

Other bolts in this price range have MIM (Metal Injection Molded) gas keys.  Don't compromise on the most critical component!  MIM parts (made from a metal powder) don't have the same shear strength as a solid billet piece of tool steel. The extractor on a 223 bolt can take a pounding even under normal use and is a common point of failure on the AR-15 platform.  Make sure you know what you are buying!  We sell parts for users who demand performance, reliability, and value.

The Checkmate 5.56 nitride bolt assembly is designed to interchange easily and run reliably in any AR-15 platform rifle chambered in 5.56 NATO, .300 AAC Blackout or .223 Remington.

The 5.56 Complete Bolt comes fully assembled with the extractor, ejector, and gas rings included.  Replace your damaged bolt with an upgrade and reuse your carrier, cam pin, firing pin, and firing pin retainer or keep a spare bolt with you in the field in case of an emergency!
