Armaspec AR10 Gun Builder's Kit – Black

This Armaspec AR10 Gun Builder's Kit provides essential small parts needed to complete an AR-10/.308 lower receiver build. Includes critical components like takedown pins, bolt catch roll pin, pivot pin detent and spring, selector detent and spring, and other oft-misplaced parts that keep builders from finishing their project. Designed for AR-10 pattern rifles, not AR-15.

All parts are machined from mil-spec materials with a durable black finish. Drop-in installation for builders with basic armorer's tools and punches. Kit eliminates the need to source individual pins and detents separately—a time-saver for both first-time builders and experienced gunsmiths stocking their bench.
