The Spike’s Tactical Delta Ring assembly is fully Mil-Spec and comes
ready for you to finish your new 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 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.
