The American Defense ADM4 Billet Lower Receiver delivers the precision geometry and ambidextrous controls of the flagship UIC lower in a clean, slick-sided profile. Machined from 7075-T6 aluminum, this billet lower delivers competition-speed reloads without the external ribbing of the UIC.

Billet machining lets American Defense cut geometry that forging can't produce, including a 20-degree competition-style beveled magwell built directly into the lower's profile to speed up reloads without adding bulk. The integral upper-to-lower tension adjustment screw lets builders dial in a precise, rattle-free fit without shims or tape, and the enlarged trigger guard keeps the rifle usable with gloves on. This lower ships with American Defense's proprietary ambidextrous magazine release, ambidextrous bolt catch and release, and dimpled takedown and pivot pins already installed. The Type III Teflon-impregnated hardcoat anodize adds surface lubricity and chemical resistance on top of standard Type III hardness. A Cerakote finish is also available.
