LBE Mil-Spec AR-15 Buffer Tube

A high quality, US-made buffer tube is a crucial component for a rifle that can stand up to wear and tear. This mil-spec AR-15 buffer tube fits the bill, with mil-spec diameter for stock compatibility, and durable 7075-T6 aluminum construction. The finish is hard-coat anodized for durability, and comes in a variety of colors to customize your build.

If you’re building out your AR-15’s recoil system completely, considering going for the LBE Buffer Tube Kit, which comes with your choice of tube, plus a buffer, buffer spring, endplate, and castle nut.
