The White Label Armory AR-15 Carbine Buffer Tube is a 6-position, mil-spec tube machined from 7075-T6 aluminum (brand part no. WLA-BUF-7010-01). White Label Armory finishes it with hard coat anodizing and a thin film lubricant to support smooth spring, buffer and carrier travel. The tube provides the mounting platform for a collapsible carbine stock or pistol brace, which makes it a common starting point for AR-15 lower builds. It follows mil-spec dimensions and is made in the USA.

Frequently Asked Questions

Does this include a buffer and spring? No. This listing is for the 6-position buffer tube only, so you add a matched buffer and recoil spring to complete the receiver extension.

Will it fit my stock or brace? It follows mil-spec dimensions, so it is intended for mil-spec stocks and braces rather than commercial-diameter hardware.

What else do I need to install it? You will want a castle nut and end plate to secure the tube during assembly.
