AR-45 80% Billet Lower Receiver – Glock Style – .45 ACP / 10MM

The AR-45 80% Billet Lower Receiver – Glock Style from New Frontier Armory is the perfect choice for building a custom AR-45. This 80% lower receiver is milled from 7075 T6 aircraft-grade aluminum billets for maximum durability and strength. It is designed to accept Glock-style large frame magazines in .45 ACP and 10MM calibers, making it an ideal foundation for your next Pistol Caliber Carbine (PCC) build.

This 80% lower is precision-machined and ready for completion, allowing you to finish it to your specifications. The magazine well is beveled for easy magazine swaps, and it comes with a proprietary magazine catch assembly and ejector already installed. The take-down pin spring and detent hole are threaded for easy set screw capturing, and the upper tension screw allows for easy adjustment of any "slop" between the upper and lower receiver.
