The LWRC IC-MKII pistol in .223 Rem/5.56 NATO with a 12.7-inch barrel and black finish (brand part no. ICMKIIP5B12SBA3) is the pistol-configured evolution of LWRC’s Individual Carbine line, built around a proprietary short-stroke gas piston system for reliability in extreme conditions. LWRC updates the upper receiver design with an M-LOK-compatible handguard and a two-position adjustable gas block, now paddle-style and located inside the rail for easy access between suppressed and unsuppressed settings. The pistol ships with flip-up front and rear sights and an SBA3 brace. Among AR pistols, this black IC-MKII favors shooters who want the added velocity of a longer piston-driven build.
