LWRC IC-M-KII 5.56 NATO 16.1" Barrel Mid-Length Gas System Rifle

The LWRC IC-M-KII delivers exceptional reliability through its proprietary short-stroke gas piston system, eliminating the fouling issues common with direct impingement designs. This 5.56 NATO rifle features LWRC's cold hammer-forged barrel and ambidextrous controls for enhanced performance in demanding conditions.

What Makes This Different

The IC-M-KII utilizes LWRC's patented short-stroke gas piston operating system, which runs significantly cooler and cleaner than traditional direct impingement rifles. The cold hammer-forged barrel with 1:7 twist rate stabilizes heavier projectiles more effectively than standard button-rifled barrels. LWRC's proprietary nickel-boron coating on the bolt carrier group reduces friction by 40% compared to standard phosphate finishes.

Key Features

• Short-stroke gas piston system eliminates carbon fouling in the receiver
• Cold hammer-forged 16.1" barrel with 1:7 twist rate for heavy bullet stability
• Fully ambidextrous lower receiver with controls on both sides
• Nickel-boron coated bolt carrier group for enhanced durability
• Mid-length gas system reduces felt recoil and muzzle rise
• Magpul MOE stock and grip with improved ergonomics
• Continuous top rail extends full length of upper receiver

Field testing demonstrates consistent sub-MOA accuracy with match ammunition, while the piston system maintains zero shift even after extended firing sessions. The rifle functions reliably in temperatures from -40°F to 140°F without lubrication changes. Law enforcement agencies report over 10,000 rounds between cleaning intervals during duty use, with the piston system preventing the bolt face fouling that plagues direct impingement designs.
