The Spike’s Tactical Delta Ring Assembly (brand part no. SDR100A) is a fully mil-spec assembly built to finish an AR-15 upper before mounting the barrel. Spike’s Tactical machines the barrel nut from tough chromoly steel, properly heat treats it, and finishes it with a phosphate coating, and the weld spring and snap ring carry the same phosphate finish per mil-spec. The delta ring itself is machined from mil-spec aluminum and finished in black anodizing. Every part in the package arrives already installed together, so a builder can quickly mount the barrel and move that much closer to a finished upper.
