The LWRC Ultra-Compact Individual Weapon stock kit delivers a practical solution for shooters building or upgrading a compact AR-15 platform. This complete buffer assembly shortens your rifle's overall length by a full inch compared to a standard collapsible stock, making it ideal for home defense, vehicle carry, tight spaces, or anyone who values maneuverability without sacrificing performance. LWRC engineered this system as a matched set—all components work together for reliable function, so install them as a package.
The FDE finish matches modern tactical aesthetics while the lightweight design keeps your rifle nimble. Four-position adjustment lets you dial in length of pull to your shooting style or gear setup, and the integral sling attachment points give you quick-deploy options. One-hand adjustments mean you can adapt your stock on the fly, even while shouldered. The rubbery buttpad grips your shoulder or plate carrier, preventing shift during recoil and rapid fire.
Inside the kit you get the shortened receiver extension (buffer tube), receiver end plate, reduced-length recoil buffer, recoil spring, and castle nut—everything required for a complete installation on a mil-spec AR lower. No hunting for compatible parts; LWRC's engineering ensures these pieces work in harmony. Whether you're running a modern sporting rifle for 3-gun, setting up a truck gun, or building a SBR, this stock system trades inches for versatility without compromise.
