UTG Pro AR-15 Mil-Spec 6 Position Buffer Tube FDE

This UTG Pro receiver extension is a 6 position, mil-spec diameter buffer tube for AR-15 rifles in a flat dark earth finish. It threads into any standard AR-15 lower and takes a mil-spec diameter collapsible stock, sold separately.

The tube is machined from aluminum with rolled threads for good engagement with the lower receiver, and tight tolerances give a zero gap fit with the stock. It takes a standard carbine buffer and spring.
