This Angstadt Arms 9mm bolt carrier group converts your AR-15 platform to fire 9mm cartridges, enabling use with pistol-caliber upper receivers. Designed specifically for blowback 9mm systems, this BCG eliminates the need for a buffer spring and works with dedicated 9mm lowers or magazine block conversions. It's a purpose-built component for shooters building or upgrading a pistol-caliber carbine.
The carrier is machined from steel and treated with a black nitride finish for corrosion resistance and reduced friction. This is a drop-in component for compatible 9mm AR-15 uppers—no gunsmithing required, though familiarity with AR-15 disassembly and reassembly is necessary for installation. Ensure your lower receiver and buffer system are configured for blowback 9mm operation before use.
