LWRC ICU5 Complete Upper Features The LWRC ICU5 Complete Upper pairs a 16 barrel with LWRC s precision manufacturing standards giving shooters a drop-in upper suited to SPR-style rifle configurations that favor a longer barrel for improved ballistics. Chambered in 5.56 the upper is built to cycle reliably across a wide range of factory and reloaded ammunition. The threaded barrel allows the installation of a muzzle brake flash hider or suppressor giving the shooter flexibility to configure the rifle for different shooting conditions. LWRC has built its name on rigorous quality control in AR platform manufacturing and this upper reflects that same standard. Finished in OD Green the ICU5 upper gives a visual departure from the standard black finish most AR uppers ship with allowing shooters to build a more distinctive rifle. As a complete upper this assembly includes the barrel bolt carrier group components and handguard needed to mate directly to a compatible AR-15 lower receiver. This makes it a straightforward way to upgrade an existing rifle or build a new one around LWRC s engineering without starting from a stripped upper. The LWRC ICU5 Complete Upper is available for sale at GrabAGun for AR-15 builders seeking a precision 16 OD Green upper.
