Our M16 profile Nitride Bolt Carrier Group is precision machined by a US government ordinance and aerospace contractor with decades of experience. This M16 bolt carrier 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 5.56 M-16 BCG.

Other BCG's in this price range have MIM (Metal Injection Molded) gas keys and extractors.  Don't compromise on those two critical components!  MIM parts (made from a metal powder) don't have the same shear strength as a solid billet piece of tool steel.  Both the gas key and extractor take a pounding even under normal use and are common points 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 M-16 5.56 Nitride Bolt Carrier Group 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 Checkmate Bolt Carrier Group assembly is built with a bolt assembly made from magnetic particle inspected (MPI) 9310 steel. 

The M16 5.56 Complete Bolt Carrier Group comes fully assembled with a bolt, bolt carrier, gas key, firing pin, cam pin, and a firing pin retaining pin.  We use the best quality US-made BCG components available and offer our complete bolt carrier group assembly at a competitive price with a Limited Lifetime Warranty!
