LWRCI takes the direct impingement AR-platform to the next level with the IC-DI! This high performance rifle features an ultra-reliable NiCorr treated Di gas block and gas tube for dependable operation in adverse conditions. One of the IC-DI more notable features is its cold-hammer forged, NiCorr-coated barrel. The barrel utilizes a unique spiral fluting, which not only looks good, but also seriously cuts down on weight and increases surface area to help speed up cooling after multiple shots.The rifle is also equipped with the LWRCI Enhanced Fire Control Group, which utilizes nickel-Teflon coated components for a smooth, crisp trigger pull with a positive reset.
