The Aero Precision 5.56 Bolt Carrier Group is among the best options on the market for a factory Bolt Carrier Group. It is made to tight tolerances, weighs just 11.52 ounces, and its MPI and HPT tested to continually check those tight tolerances. This M16 profile bolt carrier has forward assist serrations, a properly staked gas key for long lasting strength, and a Black Nitride finish for lubricity. The bolt is manufactured from Carpenter 158 tool steel to last a long time and work just as hard as you do. The bolt’s case extractor is manufactured from hard tool steel for long lasting performance and it features a black Viton O-ring insert for increased tension. Another significant detail of this bolt carrier group is the hard chrome-lined firing pin channel and hard chromed firing pin. The inner surfaces of the gas key are chrome-lined as well. The hard chrome finish on these parts significantly reduces fouling build-up and makes them extremely tough.
