American Defense UIC Billet AR-15 Lower Receiver - Ambidextrous - Cosmetic Blem

Blemished Item: Guaranteed to function correctly but may have minor cosmetic defects. Original manufacturer warranty still applies.

A billet lower receiver is the foundation of a precision AR-15 build, and the American Defense UIC Billet Lower delivers ambidextrous controls, premium 7075-T6 construction, and a competition-ready feature set at a reduced price due to minor cosmetic imperfections that have no bearing on function, fit, or dimensional accuracy.

The American Defense UIC Billet AR-15 Lower Receiver is a stripped 7075-T6 billet aluminum lower with proprietary ambidextrous magazine release, ambidextrous bolt catch/release, dimpled take-down and pivot pins, pre-installed mil-spec magazine release assembly, and Type III Teflon-impregnated hardcoat anodize or Cerakote finish — sold as a cosmetic blem at reduced price.

Billet 7075-T6 aluminum provides a higher strength-to-weight profile than forged 7075 in the areas where billet machining removes material that forging cannot, producing a receiver that is simultaneously lighter and stronger in the specific geometry that matters for competition and duty use. American Defense Manufacturing's proprietary ambidextrous magazine release and bolt catch/release lever are machined into the billet body rather than added as aftermarket bolt-ons, providing the clean, integrated ambidextrous control layout that left-handed shooters and right-handed shooters who train for support-side shooting require without the fitment concerns of external ambi conversions. Dimpled take-down and pivot pins resist walking under recoil without additional retention hardware. The cosmetic blem designation covers surface-level imperfections — minor finish inconsistencies, light tooling marks, or small cosmetic blemishes — that do not affect receiver dimensions, fit, or mechanical function.

• Material: 7075-T6 billet aluminum
• Finish: Type III Teflon-impregnated hardcoat anodize or Cerakote
• Controls: Proprietary ambidextrous magazine release, ambidextrous bolt catch/release
• Pins: Dimpled take-down and pivot pins
• Magazine Release: Mil-spec assembly pre-installed
• Platform: AR-15 pattern (mil-spec compatible)
• Condition: Cosmetic blem — function and dimensions unaffected

Mil-spec AR-15 pattern compatibility for standard upper receivers, fire control groups, stocks, and buffer systems. Ambidextrous controls are proprietary to American Defense Manufacturing and function with standard AR-15 magazines and magazine releases.

Type III hardcoat anodize with Teflon impregnation provides corrosion resistance and surface hardness exceeding standard Type III anodize, with the added lubricity that reduces wear at contact surfaces during assembly, disassembly, and operation.

An excellent value entry point for builders who want the ambidextrous control layout and billet quality of the UIC platform at a reduced price, where cosmetic surface condition on a stripped lower is irrelevant once a complete build covers the receiver under furniture and components.

American Defense Manufacturing backs the UIC Lower with their standard warranty — the blem designation applies to cosmetics only, with full functional warranty coverage retained.
