The Battle Arms Development Authority Elite is an ambidextrous, lightweight billet AR-15 upper and lower receiver set machined from 7075-T6 aluminum and finished in black anodize (brand part no. AE-SET-BLK). Battle Arms Development designs the set around a patent-pending lightweight profile that removes weight without giving up the strength of billet. The lower accepts standard mil-spec AR lower parts and is cut to take the company’s short-throw ambidextrous safety selectors. It is a solid starting point for a custom AR-15 build where light weight and ambidextrous operation are priorities.

Key Specifications

• The receivers are CNC-machined from billet 7075-T6 aluminum, an aerospace-grade alloy known for strength at low weight.
• The finish is MIL-A-8625F Type III Class 2 hard anodize in black, a tough coating that resists wear and corrosion.
• The patent-pending lightweight design trims weight from the receivers without compromising rigidity.
• The lower has a built-in ambidextrous bolt release and magazine release, so the rifle runs the same from either shoulder.
• Selector markings and relief cuts support a standard 90-degree safety or the BAD-ASS-ST and BAD-CASS-ST short-throw ambidextrous selectors.
• The magazine well is flared and deeply beveled, which helps guide magazines in during fast reloads.
• The lower has an integrated trigger guard machined into the receiver, which builds the guard into the receiver rather than adding a separate part.
• The lower is compatible with TDP and mil-standard AR lower parts, so common triggers, grips and stocks fit.
