 The Angstadt Arms dedicated .45 ACP AR lower and upper receiver set is designed for compatibility with all your favorite parts. This pistol caliber lower receiver accepts all aftermarket and factory double stack .45 ACP Glock magazines and can be assembled with Mil-Spec AR-15 parts. The only dedicated .45 caliber part required for the upper and lower receiver assembly is a bolt allowing you to use your favorite trigger, pistol grip, safety, and bolt release. The Angstadt Arms .45 AR upper receiver and lower are machined from billet 7075-T6 aluminum with no forward assist or dust cover. Because it is from billet, features like a flared magwell and integral trigger guard can be machined directly into the receiver. It also features a last round bolt hold open mechanism which is not common on other pistol caliber AR-15 receivers. Build the ultimate AR-45 with the Angstadt Arms .45 caliber receiver set.
