All of our USGI parts are hand selected. Our parts are what you need for the finishing touches of that new retro rifle build or to restore or upgrade your retro rifle or SP1. Our USGI parts are correct for all M16A1 and M16-series rifles.

In a world of tacticool AR15s with rails and red-dots, I really wanted to make a throwback build to the M16A1 style: lightweight and 1960s space age vintage.  Robert’s Expert Grade Armory Upgrade furniture was the pièce de résistance of my build.  The original handguard/stock/grip that came with my retro build parts did not match and were made from different materials and were in poor shape.  The Armory Upgrade from USCO, however, was perfect: the colors and materials matched, and made the rifle look like it rolled off the line in 1969.  Would recommend this to anyone who wants a sharp looking retro-AR15 build.

Just want to say thanks for having the grips and stock for my AR build, perfect fit and looks really cool. All my friends who build ARs were really impressed with the quality of hand guard and stock.
