Battle Arms Development AE-LR-BLK 223 Rem/5.56 NATO Billet Aluminum Stripped Lower

The Battle Arms Development AE-LR-BLK is a stripped AR-15 lower receiver engineered around a patent-pending lightweight billet design. Marked 223 Rem/5.56 NATO for multi-caliber use, it serves as the serialized foundation for assembling a custom AR-pattern rifle or pistol backed by Battle Arms Development's reputation for precision manufacturing.

This lower is CNC-machined from a single block of 7075-T6 aerospace aluminum, the industry-standard alloy for premium AR receivers. Every contour is cut from solid billet - not forged - allowing the tightest tolerances and the company's signature lightweight profile without sacrificing the rigidity needed for service use. The receiver is finished in a hard anodized black coating that meets MIL-A-8625F, Type III, Class 2 military specifications, providing long-lasting wear and corrosion resistance.

Proudly made in the USA, the AE-LR-BLK ships as a stripped lower only - no lower parts kit, grip, stock, trigger, or magazine is included.
