The Ruger AR Buffer Tube Kit gives you the factory-quality parts to complete or repair an AR-pattern lower. Built to Ruger's manufacturing standards, the kit centers on a mil-spec-pattern receiver extension that accepts standard carbine stocks, along with the supporting components needed to get a lower buttoned up and running. Whether you are finishing a build, replacing a worn assembly, or keeping spares in the parts bin, factory components from a major American maker take the guesswork out of compatibility and quality.
