LWRC UCIW Ultra Compact Individual Weapon Stock System Complete Kit Black 200-0092A01

Overview

The LWRC Ultra Compact Stock Assembly (UCIW) is a lightweight stock kit designed for AR-15 and M16 platforms to shorten the firearm's overall length by a full inch compared to a standard setup. The synthetic black stock features an upswept toe to prevent snags on chest rigs or body armor, an integrated sloped cheek rest for comfortable alignment, and integral sling attachment points that accept push-button QD sling swivels. A rubber buttpad prevents slippage during firing, while the four-position receiver extension allows the user to adjust the length of pull. Overall length of the assembly measures 5.75 inches collapsed and 9 inches at maximum extension. The kit includes the stock, receiver extension, index plate, proprietary buffer, recoil spring, and castle nut; these components are engineered to work together and should be installed as a complete system for reliable performance.
