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.

Black Hard anodized with a surface hardness of 60 Rockwell
Features a nylon tipped tensioning screw to ensure the solid fit between upper and lower maintains for years to come.
Functions with nearly all available AR parts kits and uppers.
Flared mag well
Pictogram safe and fire indicators
Chevrons on the front of the mag well and the distinctive Grey Ghost markings tie the Cornerstone to the Specter Series of Rifles from Grey Ghost Precision.

GORGEOUS. Seriously great lower. October 9, 2017
Reviewer: Johnny @ 180 Second Ideas from East Tennessee  
Used The Cornerstone on a recent build and it is absolutely gorgeous. The finish is maybe the best I have ever seen on any AR part. I know that's a bold statement, but after 4 months of owning and using this lower...I stand by it. The skull is cool and the simple GGP is totally fine. Fit was great with my other parts, and overall I could not be happier. LOVE IT.
