LWRC IC-MK II SBR 5.56mm 12.7″ Threaded Barrel – Flat Dark Earth

The LWRC IC-MK II SBR in 5.56mm NATO delivers elite short-barrel performance in a flat dark earth finish, purpose-built for operators and serious enthusiasts who demand the best from a compact rifle platform. Chambered in 5.56mm NATO, this short-barreled rifle features a 12.7-inch cold hammer-forged, spiral-fluted barrel with a threaded muzzle, combining exceptional durability with suppressor-ready versatility.

Built around LWRC’s renowned self-regulating short-stroke gas piston operating system, the IC-MK II eliminates the heat and carbon fouling associated with traditional direct impingement designs, resulting in a cooler, cleaner, and more reliable action in all conditions. The nickel-phosphate-coated bolt carrier group ensures enhanced corrosion resistance and smooth cycling even under sustained fire.

The rifle features LWRC’s fully ambidextrous lower receiver with ambidextrous controls — including safety selector, bolt catch/release, and magazine release — making it equally capable in either hand. The monolithic upper receiver integrates a continuous top rail for seamless optics mounting with no rail gaps, while the LWRC UROS modular rail system provides flexible M-LOK accessory attachment at the 3, 6, and 9 o’clock positions.
