Angstadt Arms .45 ACP Bolt Carrier Assembly, QPQ Black Nitride, 8620 Steel, AR-15

The Angstadt Arms Bolt Carrier Assembly (brand part number AA45BCGNIT) is machined from 8620 alloy steel and finished with a QPQ black nitride treatment, built for AR-15 uppers chambered in .45 ACP that feed from GLOCK-pattern .45 ACP magazines. It runs with a standard AR-15 hammer, so there’s no need for caliber-specific fire control parts, and it features a removable weight for shooters running a Law Tactical folding stock adapter. It’s a purpose-built carrier for anyone building a GLOCK-mag-fed .45 ACP AR pistol or carbine.
