JE Machine Tech PS-BTP AR-15 Pistol Buffer Tube - Black

The JE Machine Tech PS-BTP is a precision-machined AR-15 pistol buffer tube (receiver extension) cut from 6061-T6 aluminum and finished in a rugged matte-black Type II anodized coating. Designed as a direct replacement for the factory Mil-Spec tube on AR-15 pistol platforms, the PS-BTP threads onto any standard AR-15 lower receiver and accepts the standard buffer spring, buffer, castle nut, and end plate used throughout the AR-15 platform.

Built to standard Mil-Spec dimensions for an AR-15 pistol extension, the PS-BTP drops into existing pistol builds with no fitting required. The lightweight aluminum construction keeps the tube from upsetting the balance of a finished AR pistol while providing the strength needed for hard use on the bench or in the field. A foam cap is included to keep debris out of the tube interior during storage and transport.

Like every JE Machine Tech component, the PS-BTP is made in the USA and inspected for proper fit and finish before it ships. Whether you are assembling a new AR-15 pistol, replacing a worn-out buffer tube, or simply keeping a spare on hand for the workbench, the PS-BTP delivers the proven Mil-Spec geometry and quality AR builders expect from JE Machine Tech.
