BROWNELLS AR-15 STOCK ASSY COLLAPSIBLE COMMERCIAL

Collapsible buttstock similar to the current USGI M4 carbine stock provides convenient six-position length-of-pull adjustment to fit different-size shooters, including those wearing body armor.

Steel lock nut has four square notches and pre-cut detents for staking to lock plate. Heavy duty, machined aluminum receiver extension, hardcoat anodized for extra strength, stands up to the punishment of harsh tactical operations.
