Dark Storm Industries DS-15 Barrel Nut/Delta Ring Kit 5.56mm

Dark Storm Industries DS-15 Barrel Nut/Delta Ring Kit 5.56mm. This kit is recommended for mid and heavy barrels with tightened down precision MOA settings. If you need a replacement consider picking up a new set. The barrel nut/delta ring is heat treated for steel (not soft steel like some other brands) and the weld spring is steel with a phosphate finish. When installed properly the delta ring will out perform any other ring on the market. We always recommend testing your ring/delta ring at you
