For those embarking on an AR build, the Cornerstone lower provides the ideal beginning point. Meticulously machined from forged 7075-T6 aluminum, it exhibits tighter than Mil-Spec tolerance and includes a nylon tipped tensioning screw for solid upper and lower fit assurance.
Key features of this unit include a flared mag well, clearly defined pictogram safe and fire indicators, front mag well chevrons, and the unique Grey Ghost markings. This versatile lower is compatible with the vast majority of available AR parts kits and uppers.
PLEASE NOTE: Completion of this lower requires a separately purchased lower parts kit, buffer, and stock of your preference.
