Grey Ghost Precision Cornerstone AR-15 Lower Receiver
The lower receiver is the cornerstone of any AR build. A lack luster lower can vary widely in final specs and negatively impact your build's reliability. Start your AR-15 build off with a solid foundation using Grey Ghost Precision's Cornerstone stripped lower!

A proper MIL-SPEC lower receiver's dimensions can vary over .005" or more from one receiver to the next. This is fine for a military rifle, but these tolerance errors can stack up, impacting parts compatibility, fit, and function, especially when using aftermarket components. By comparison, the Cornerstone lower receiver is machined to exceptionally tight +/- 0.001" tolerances, allowing for incredible consistency. To further increase accuracy, this lower features a nylon tipped tension screw, ensuring your upper and lower fit together without rattle.
