The UTG PRO Ops Ready S3 Mil-Spec stock kit in black (Leapers part no. RBUS3BM) is a complete six-position collapsible stock set for AR-15 rifles from Leapers. The kit includes the polymer stock, the mil-spec six-position extension tube, a buffer, a buffer spring, a tear-drop ring and a castle nut. The stock is molded from impact-resistant, high-strength polymer, and the mil-spec diameter tube is precision machined from aircraft-grade aluminum with rolled threads and anodized for corrosion and wear resistance. A built-in rubberized buttpad and slanted cheek rest help with stability and consistent control. It is designed and made in the USA.
