Upper Receiver and Barrel

The 6061 aluminum PCC AR-15 billet upper receiver with a black anodized finish forms the core of the front end for the AR-45 platform. The Bear Creek Arsenal 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 tubular freefloat M-LOK handguard in black anodized aluminum surrounds the barrel along the compact forend with a 1.77-inch internal diameter that provides clearance for suppressor use when a suppressor is threaded onto the barrel. The handguard uses a proprietary barrel nut for attachment and features M-LOK slots along the handguard body for accessory attachment.

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 black anodized aluminum Mil-Spec 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.
