American Defense UIC AR-15 Lower Receiver - Ambidextrous - Stripped Lower

The American Defense UIC Billet Lower Receiver delivers the heart of the Universal Improved Carbine platform for builders who want to assemble their own.

Machined from a solid billet, this lower is 40% stronger than a traditional mil-spec receiver while adding only half an ounce of weight, and the Type III Teflon-infused hardcoat anodized finish protects against wear and corrosion for long-term use. The UIC lower ships with a truly ambidextrous bolt catch and magazine release pre-installed from the factory, and the 20-degree flared magwell speeds up magazine changes under pressure. Dimpled takedown pins make disassembly easier, and a tension screw installed near the grip screw eliminates wobble between receivers. Note that this lower isn't compatible with triggers that require external anti-rotation plates or screws, though ADM offers a trigger pin kit for CMC triggers and the lower is fully compatible with standard GI, Geissele, and other drop-in triggers using standard pins.

American Defense Manufacturing was founded on the idea of building dependable AR-15 components without cutting corners. All ADM products are designed and built with U.S.-sourced material in New Berlin, Wisconsin.
