Advanced Technology AR-15 Pistol Buffer Tube Assembly

The Advanced Technology AR-15 Pistol Buffer Tube Assembly (brand part number A.5.10.2518) gives pistol-brace builders a complete buffer tube setup in one part number, machined from 6061-T6 aluminum for a lightweight, corrosion-resistant foundation. ATI includes the AR-15 recoil plug and buffer spring along with a steel mil-grade e-coated castle nut locking ring, so the whole system arrives ready to install without hunting down individual hardware pieces. Because it’s sized specifically as a pistol buffer tube rather than a stock-length tube, it’s built for a brace-equipped AR-15 pistol build rather than a collapsible-stock carbine.
