Toolcraft Black Nitride BCG 9310

  • Toolcraft makes some of the best AR15 bolt carrier groups on the market today. Precision manufactured on state-of-the-art CNC machinery in North Carolina, Toolcraft products are trusted by the U.S. Military and carry a lifetime warranty.

    A bolt carrier group is only as good as it’s bolt. This bolt is manufactured from 9310 Steel which is a modern ultra-high strength steel designed specifically for applications where high strength and durability are of paramount importance. Also see our Carpenter 158 steel Black Nitride BCG.

    Finish is Black Nitride which is a metal treatment that produces a case-hardened surface. The resulting finish is extremely wear and corrosion resistant and very slick. This means less friction and smoother, more reliable function. The rich black color on these BCGs looks fantastic and cleans up way easier than a phosphate finish. Also see our Nickel Boron BCGs. See menu for more AR15 parts.

  • This is a 223/5.56/300 Blackout bolt carrier group.

    This AR BCG will not work with 6.5/6.8/308 etc.
