Product Description The LWRC UCIW (Ultra-Compact Individual Weapon) stock system is designed to shorten the overall length of your AR-15 by approximately one inch compared to a standard collapsible stock assembly, while maintaining reliable performance through a matched, purpose-built component set. This complete kit includes the UCIW stock in Flat Dark Earth (FDE) along with a compact receiver extension (buffer tube), receiver end plate, shortened recoil buffer, recoil spring, and castle nut. Built for mil-spec compatibility, the lightweight stock features integral sling attachment points, easy one-hand length-of-pull adjustments, and an excellent cheek weld, with a rubber buttpad to help prevent slippage during firing. The receiver extension offers four positions for adjustable fit.
