The LWRC UCIW Ultra Compact Stock Kit Black is a purpose-built AR-15/M16 stock system that trims roughly an inch off overall length compared to standard collapsible setups. This complete kit pairs a compact receiver extension, shortened buffer, and tuned recoil spring with a lightweight synthetic stock that maintains a solid cheek weld and dependable cycling when used as a matched system.

Designed for shooters who want a shorter, more maneuverable rifle without sacrificing comfort, the UCIW stock offers four length-of-pull positions, integral sling attachment points, and a non-slip rubber buttpad to keep the rifle planted during rapid strings of fire. It is well suited for compact carbines, range use, and training builds where space efficiency and smooth handling matter, reflecting LWRC’s focus on thoughtful engineering and reliable performance.
