LWRC ICPSD Upper Features The LWRC ICPSD Upper is built around an 8 inch threaded barrel chambered in 5.56 NATO placing it among the shortest barrel lengths LWRC offers for its Individual Carbine platform. This short length is well suited to pistol builds or short-barreled rifle configurations where maneuverability in tight spaces takes priority over maximum velocity. The threaded muzzle gives builders the option to add a flash hider compensator or suppressor with the PSD designation suggesting a setup optimized for use with a sound suppressor. A short barrel paired with a quality gas system helps keep the action cycling reliably despite the reduced dwell time inherent to shorter lengths. Finished in black the ICPSD Upper carries LWRC s established reputation for precision machining and reliable function across its Individual Carbine lineup. Manufactured entirely in Cambridge Maryland this upper reflects the same build quality LWRC applies to its longer barreled rifles scaled down into a compact package. Builders working on a dedicated short-barrel or suppressor-focused project can mount this upper onto a compatible Mil-Spec lower to complete their build. Available for sale at GrabAGun the LWRC ICPSD Upper is a strong option for anyone assembling a compact close quarters 5.56 platform.
