Ruger 91006 AR-15 Buffer Tube Kit 6-Position Mil-Spec 7075-T6 Aluminum

The Ruger 91006 is a complete AR-15 buffer tube kit built to Ruger's standard of rugged reliability and designed for use with mil-spec AR-15 pattern firearms and receivers.

The tube is constructed from 7075-T6 impact-extruded aluminum, delivering a lightweight but exceptionally strong foundation that stands up to the recoil and abuse of regular AR-15 and M4 platform use.

A 6-position mil-spec design lets you adjust length of pull to fit a wide range of shooters and shooting positions, making it a versatile drop-in solution for both carbine and full-length AR builds.

The kit includes everything needed to complete an AR-15 lower assembly: the buffer tube, buffer spring, buffer weight, end plate, and castle nut, giving you all the core components on hand for installation.

Engineered for compatibility with standard mil-spec AR-15/M4 receivers, the 91006 Buffer Tube Kit provides a strong, lightweight backbone for any modern sporting rifle build and is backed by Ruger's reputation for quality. Overall length is 13.90 in.
