JE Machine Tech PS-BTP3 AR-15 7.19" Pistol Buffer Tube Fluted 6061 Aluminum Black

The JE Machine Tech PS-BTP3 is a purpose-built AR-15 pistol buffer tube precision-machined from 6061 aluminum and finished in a durable Type II anodized black coating. At 7.19" long, this fluted receiver extension is sized for AR-15 pistol platforms and features six full-length weight-cutting flutes machined into the tube body. The flutes trim mass without sacrificing strength, bringing the finished tube in at a lightweight 3.5 oz.

Cut to Mil-Spec threads and following the standard AR-15 pistol buffer tube profile, the PS-BTP3 drops directly into any AR-15 lower receiver built around a pistol-style carbine extension. The hardcoat anodized surface stands up to repeated handling, holster wear, and field use, while the fluted exterior gives the build a distinctive, purpose-built look over a standard solid tube.

Whether assembling a new AR-15 pistol from the ground up or replacing a heavier factory tube on an existing build, the JE Machine Tech PS-BTP3 delivers a lightweight, duty-ready fluted buffer tube that pairs cleanly with any standard AR-15 pistol buffer and spring setup.
