The Spike’s Tactical Delta Ring assembly is fully Mil-Spec and comes ready for you to finish your upper. The barrel nut is machined from tough chromoly steel, is properly heat treated, and of course completed with a phosphate finish. We also finished the weld spring and snap ring in a phosphate finish per Mil-Spec. The delta ring itself is made of Mil-Spec aluminum and features a black anodized finish. Inside the package you’ll find everything already installed so you can quickly mount your barrel and get that build one step closer to being finished.
