Premium Billet 80% Lower Receiver: The Builder’s Solution.
You’re looking at the lower that fixes the problems other brands ignore. This isn’t just another piece of aluminum; it’s a direct result of builders telling us what they hate about their 80% builds. We listened. This Premium Billet lower is engineered to turn the most frustrating steps of your AR-15 build into simple, straightforward work.
Stop Fighting Spring-Loaded Pins. Start Building.
The biggest upgrade here isn’t just visible—it’s tangible during assembly. We’ve machined threaded holes for both the bolt catch release pin and the rear takedown pin detent. No more chasing a spring across your garage floor or using a punch that slips. You install these critical components with the provided screws and a hex key. It’s secure, it’s clean, and it saves you a half-hour of aggravation. Once you build with this system, you’ll never want to go back to the old, frustrating method.
Built from the Ground Up for Performance
We start with a solid block of American-sourced 7075-T6 aluminum billet. This isn’t forged; it’s CNC-machined from a single piece of material, giving us superior control over tolerances and strength. The result is a receiver with a noticeably more rigid feel and exceptionally clean lines. The magwell is professionally broached for smooth, reliable magazine insertion and ejection every time.
The “FIRE” and “SAFE” engravings are deep, laser-etched, and filled for permanent legibility. The entire receiver is finished in a durable, Mil-Spec Type III hardcoat anodizing in matte black. It’s a finish that stands up to handling, weather, and use.
