The Lantac UAR 7075-T6 Billet Upper Advanced Receiver is built for shooters who want a smoother, more refined AR-15 experience. Precision machined from certified 7075-T6 aluminum and finished in a deep black Type III Class 2 hardcoat anodize, it features Lantac’s patent-pending Smoothcam system with a domed, low-friction cam pin and blended cam recess that work together to reduce bolt carrier drag and internal wear.

This stripped billet upper is ideal for premium AR builds focused on reliability, consistency, and clean cycling at the range or in training. Its ultra-smooth proprietary bore, concentric barrel nut threads, and M4 feed ramps support accurate, repeatable performance with standard AR components. The Lantac UAR showcases the brand’s attention to detail and commitment to high-end machining in modern AR platforms.
