Lower Receivers

Wolfpack Armory AR-45 / AR-10MM Stripped Lower Receiver | Glock Magazine Compatible | Billet Aluminum

Build a reliable pistol-caliber carbine with the Wolfpack Armory AR-45 / AR-10MM Stripped Lower Receiver. Precision machined from billet aluminum, this lower is engineered specifically for 10mm Auto and .45 ACP AR platforms while maintaining compatibility with standard Mil-Spec AR-15 components.

Designed around Glock-pattern magazines, the receiver accepts Glock 20 pattern 10mm magazines and compatible .45 ACP Glock-pattern magazines, giving builders the flexibility to configure either caliber using the same platform.

Unlike many PCC lowers, the Wolfpack receiver incorporates an integrated ejector and pre-installed magazine catch, simplifying assembly and improving reliability.
