Product DescriptionThe Grey Ghost Precision Cornerstone stripped lower receiver is built to serve as the foundation of an AR-style rifle build. Machined from forged 7075-T6 aluminum and finished in black anodizing, this multi-caliber lower is made to tighter-than-Mil-Spec tolerances for a precise fit. It features a nylon-tipped tensioning screw to help create a solid upper-to-lower fit, along with a flared magazine well for smoother reloads. Additional details like pictogram safe and fire indicators, front mag well chevrons, and signature Grey Ghost markings give this receiver a clean, functional, and distinctive appearance.
