LWRC IC MKII 5.56mm Semi-Automatic Rifle – 16.1″ Barrel, Black, 30+1 Capacity

The LWRC IC MKII in 5.56mm NATO is a premium American-made direct impingement AR-15 platform engineered for shooters who demand exceptional reliability, precision, and out-of-the-box performance. Built on LWRC’s renowned Individual Carbine MKII platform, this rifle features a 16.1-inch cold hammer-forged barrel with LWRC’s proprietary NiCorr surface treatment for outstanding corrosion resistance and barrel longevity. The IC MKII incorporates LWRC’s fully ambidextrous lower receiver with ambidextrous bolt catch/release, magazine release, and safety selector—making it equally capable in the hands of left- or right-handed shooters.

The rifle ships with a 30-round magazine and is chambered in 5.56mm NATO, providing compatibility with both 5.56 NATO and .223 Remington ammunition. LWRC’s self-regulating short-stroke piston gas system delivers cleaner, cooler, and more reliable cycling compared to traditional direct impingement designs—reducing carbon fouling and minimizing heat transfer to the bolt carrier group. The MKII’s enhanced bolt carrier group features a fully staked gas key and a proprietary NiCorr-treated bolt for extended service life.

Additional features include LWRC’s iconic UROS (Ultra Reliable One-piece Skeletonized) handguard with full-length M-LOK slots for modular accessory attachment, a Magpul MOE stock and pistol grip for ergonomic comfort, and a Nickel Boron-coated fire control group for a crisp, consistent trigger pull. The matte black finish and monolithic upper receiver design provide both durability and a clean aesthetic.
