Spike's Tactical Delta Ring Assembly with Nut for AR Rifles - SDR100A

The Spike's Tactical Delta Ring Assembly with Nut for AR Rifles is a fully Mil-Spec upper receiver component designed for builders who want a proven, ready-to-install solution. This complete delta ring assembly arrives with all components pre-assembled—barrel nut, weld spring, snap ring, and delta ring—so you can skip the fiddly setup and move straight to mounting your barrel. Whether you're finishing a precision rifle build or refreshing an upper, this assembly takes the guesswork out of sourcing compatible parts that actually work together.

Spike's builds this assembly to military specification standards. The barrel nut is machined from chromoly steel, heat-treated for durability, and finished in phosphate to resist corrosion. The weld spring and snap ring are phosphate-finished as well for consistency and longevity in the field or at the range. The delta ring itself is Mil-Spec aluminum with a black anodized finish—traditional, proven, and built to handle thousands of rounds without failure or creep.

If you're assembling an AR or swapping uppers, this is the kind of straightforward, no-nonsense component that lets you focus on the rest of your build. Everything comes ready to go, and the Mil-Spec credentials mean it'll play nice with standard AR parts and upper receivers.
