The LWRC IC MK II Rifle (LWRC part no. ICMKIIR5TG16) runs LWRCI’s proprietary short-stroke gas piston operating system for unmatched reliability in extreme conditions with genuinely easy maintenance. Chambered in 5.56 NATO and also safe for .223 Remington, it’s built around a 16.1-inch cold hammer forged spiral-fluted barrel and a Monoforge one-piece upper receiver for a strong, precise foundation. Every control is ambidextrous, including the bolt catch, bolt release, magazine release, safety selector, and charging handle, making the rifle equally fast for left- and right-handed shooters. A nickel boron coated bolt carrier, LWRCI Skirmish back-up sights, and an LWRCI compact stock and pistol grip round out a rifle that ships with a 30-round Magpul PMAG.
