Directly descended from the rifles developed by LWRCI™ to meet the requirements for the U.S. Army Individual Carbine program, the IC-SPR is built for high performance. The IC-SPR variant is one of our most popular IC models. Constructed using the highest quality materials, built on our patented self-regulating short-stroke gas piston system, machined from materials that belong to the super alloy family of steel alloys most often used in aerospace, LWRCI™ raises the bar on reliability and ease of maintenance- delivering the highest level of performance. The gas-piston system can be accessed quickly by loosening two thumb screws. The IC-SPR with one-piece Monoforge™ upper design includes an integrated rail-base that is stronger and lighter. The 12” user configurable rail system with individual rail sections allow the shooter to place accessory rails where they are needed while maintaining its low profile ergonomic fit and function.
