The UTG PRO Model 4 S2 Stock Kit is a complete 6-position mil-spec stock assembly built for AR-15 rifles. Its high impact reinforced polymer construction pairs with an ergonomically chamfered rubberized butt pad and a slanted cheek rest to support stable, consistent shooting.
The kit includes a mil-spec receiver extension tube, buffer, buffer spring, tear-drop ring, and castle nut, so it carries everything needed for a full stock installation or upgrade. The aircraft aluminum extension tube is hard coat anodized, and the black finish has dehorned corners for snag-free handling.
