Bear Creek 7.5-Inch .45 ACP Barrel

The Bear Creek 7.5-inch barrel is machined from 4150 CrMoV steel to an M4 contour profile with a phosphate finish and a 1-16 twist rate chambered in .45 ACP. The .578x28 threaded muzzle is the standard thread pitch for .45 ACP AR-pattern builds, and the KAK Industry .45 ACP compensator included in this kit is matched to that specification. The compact 7.5-inch length suits pistol configurations within the AR-45 platform.

6061-T6 Billet Upper Receiver

The billet upper receiver in this kit is machined from 6061-T6 aluminum with a Type 3 Class 2 hardcoat anodized finish. This is a pistol caliber AR-15 compatible design, distinct from standard mil-spec upper receivers, and is suited to .45 ACP blowback platform builds. The billet construction and hardcoat anodizing provide a dense, wear-resistant exterior finish across the receiver body.

7-Inch M-Lok Handguard

The 7-inch M-Lok handguard is constructed from aluminum in black with a partial Picatinny top rail section running along a portion of the top of the handguard. M-Lok attachment points along the remaining surfaces support compatible accessories. The freefloat design keeps the barrel free from handguard pressure, and the 7-inch length is closely matched to the 7.5-inch barrel for a compact overall profile.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are not included.
