Upper Receiver and Barrel

The PCC billet AR-15 upper receiver with a black finish forms the core of the front end for the AR-45 platform. The 7.5-inch M4 contour 4150 CMV steel barrel brings a Parkerized finish and a 1-16 twist rate to the .45 ACP chamber, threaded at .578x28. This upper operates on a direct blowback system, meaning there is no gas tube or gas block present or required on this upper. The 7-inch freefloat M-LOK handguard in black aluminum surrounds the barrel along the compact forend with M-LOK slots for accessory attachment and an integrated hand stop positioned along the handguard body.

Bolt Carrier Group and Charging Handle

The PCC AR bolt assembly is the platform-correct bolt assembly for the .45 ACP AR-45 blowback build. The Mil-Spec AR-15 charging handle pairs with the bolt assembly inside the upper receiver to complete the upper interior. These two components complete the upper component set alongside the upper assembly and barrel.
