The lightest AR stock ever devised! Weighs only 5 oz. This stock uses Ace’s original soft foam overtue for the ultimate cheek weld. A billet machined gusset reinforces the receiver extension tube at it’s weakest point - directly behind the receiver. Precision machined aluminum butt clamps directly to the RET and provides a machined in sling mount. Also includes 1/2” buttpad and buffer tube.
