The UTG Pro Model 4 Mil-Spec OPS Ready Black Synthetic Buttstock Kit delivers heavy-duty performance with tight tolerance controls that ensure a secure fit and reliable function. The mil-spec stock is molded from impact-resistant, high-strength polymer in black, while the mil-spec diameter extension tube is precision-machined from aircraft-grade aluminum with rolled threads and anodized for superior corrosion and wear resistance. An ergonomically chamfered built-in rubberized butt pad and slanted cheek rest enhance shooting stability and promote consistent firearm control.
Dual storage compartments with removable waterproof caps provide dry storage for batteries (up to 8 CR123) or other accessories. The stock features an integral ambidextrous sling loop and QD mount, with an extended 8″ length for length of pull. This kit includes the polymer stock, mil-spec 6-position extension tube, buffer, buffer spring, tear-drop ring, and castle nut. Fully dehorned corners and melted contours eliminate snag points and increase comfort during operation. Proudly made in USA.
