AR-15 Stripped Forged Upper Receiver Black

Cornerstone Lower fans have been asking for years now; "Does GGP make a forged upper with the same gorgeous anodizing and tight fit as their lower?" Ask and ye shall receive! Finally, you can grab what Grey Ghost Precision considers the best forged upper in the biz, and it is a perfect companion for your GGP Cornerstone Lower receiver.
