The LWRC IC MKII in 5.56 NATO is a modern AR-platform rifle family built around LWRC’s short-stroke gas piston system and monolithic-style upper. Available in Black or FDE and offered in three configurations — 10.5″ pistol, 14.7″ pinned rifle, or 16″ rifle — the IC MKII combines a stiff one-piece upper, a cold-hammer-forged barrel, and ambidextrous controls for a versatile duty or sporting platform.
Designed for reliability and user ergonomics, the IC MKII includes LWRC’s short-stroke piston operation (designed to reduce fouling in the receiver), a cold-hammer-forged 1:7 twist barrel with Black Nitride finish, nickel-boron coated bolt carrier, and LWRC-designed furniture and controls. The rifle ships with LWRC Skirmish backup iron sights, an A5 two-position gas block, ambidextrous charging handle and lower controls, an advanced trigger guard, Ultra Combat grip, compact stock, and a Magpul 30-round PMAG.
