Advanced Technology AR-15 Pistol Buffer Tube Assembly

The Advanced Technology AR-15 Pistol Buffer Tube Assembly is a complete drop-in kit built specifically for AR-15 pistol platforms that call for a shorter, non-Mil-Spec buffer tube. Designed as a direct-fit replacement or finishing component for new pistol builds, the assembly provides all of the major parts needed to get an AR-15 pistol lower up and running.

The kit includes the pistol buffer tube, a steel Mil-grade e-coated castle nut, locking ring, AR-15 recoil plug, buffer spring, and pistol buffer tube end cap. The castle nut and locking ring are e-coated for corrosion resistance, and every component in the kit is matched to install cleanly together on a standard AR-15 lower receiver configured for a pistol-length tube.

Whether you are completing a fresh AR-15 pistol build or refreshing worn or missing components on an existing pistol platform, this Advanced Technology buffer tube assembly delivers the core hardware in one convenient package. Overall dimensions are 2.75" x 3.50" x 14.00" (H x W x L).
