Product Info for Grey Ghost Precision Forged Upper Receiver

Cornerstone Lower fans have been asking for years now; Do you make a forged upper with the same gorgeous anodizing and tight fit as your lower? Ask and ye shall receive!image

Finally you can grab what we consider the best forged upper in the biz, and it is a perfect companion for your GGP Cornerstone Lower receiver. After all, accuracy comes from tight, precise tolerances that minimize all variables from the moment the hammer strikes the firing pin until the round leaves the muzzle. By perfecting the critical tooling dimensions to the smallest degree, a forged receiver can punch the same hole down range.
