The Brownells AR-15 Stock Assembly Collapsible Commercial Black is a collapsible buttstock similar to the current USGI M4 carbine stock that provides convenient six-position length-of-pull adjustment to fit different-size shooters, including those wearing body armor. Built from aluminum and fiberglass-reinforced, injection-molded nylon in matte black, this assembly measures 8¾” overall length when collapsed and 11¾” when fully extended.
Ready to install on any standard AR-15 rifle or carbine lower receiver, this assembly includes a 1.17″ diameter commercial buffer tube, receiver lock plate, lock nut, toe-mounted steel sling loop, carbine recoil spring and buffer. The buttstock is made from extremely tough, fiberglass-reinforced, injection-molded nylon that resists impact, heat, moisture, extreme cold, and most cleaning solvents, with stock interior diameter matched to buffer tube O.D. for a snug fit that eliminates unwanted play and rattles. It enables you to convert a fixed-stock, flattop rifle to M4 carbine configuration without permanent alterations to your gun. Made in the U.S.A. with a Forever guarantee.
