This Premium 45 caliber Bolt Carrier Assembly is compatible with all 45 caliber Glock style Pistol Caliber AR builds. Maintaining a harder core than standard 8620 steel, this carrier is machined from Premium 4340 Steel. The outside diameter is precision ground prior to machining in a pre-hardened state for improved tolerances post machining and coating.
