LWRC ICU5 Complete Upper Features The LWRC ICU5 Complete Upper ships as a ready to install assembly chambered in 5.56 giving an AR-15 builder a drop on option that avoids the complexity of sourcing and headspacing individual upper components separately. A 16 threaded barrel keeps the upper at a common and versatile overall length suitable for a wide range of uses from home defense to range shooting while the threaded muzzle allows the owner to add a brake flash hider or suppressor as needed. Building this upper to LWRC s own manufacturing standards means the barrel bolt carrier group and gas system are matched and tested together rather than assembled from unrelated parts. This complete upper design saves significant build time for anyone assembling or upgrading an AR-15 pattern rifle. Finished in Patriot Brown the ICU5 upper gives a rifle a distinctive look that stands apart from the black or standard FDE finishes common across the AR market. That unique finish lets a builder create a visually distinct rifle while still relying on LWRC s reputation for quality manufacturing. Pairing this upper with a compatible AR-15 lower receiver is all that is needed to complete a functioning rifle making it an efficient option for a builder who already has a lower on hand. For anyone looking to build or upgrade an AR-15 with a factory matched 5.56 upper in a standout finish the LWRC ICU5 Complete Upper is available for sale at GrabAGun.
