Cornerstone; “the chief foundation on which something is constructed or developed” When you want to start your AR build, the lower is the starting point. The fit and finish of our cornerstone will prove to you that you have the right beginning to a reliable and strong AR build. When coupled with our Grey Ghost Precision uppers, the match is very hard to beat.

  • Chevrons on the front of the mag well and the distinctive Grey Ghost markings tie the Cornerstone to Rifles from Grey Ghost Precision.
