The LWRCI™ SPR | Individual Carbine- Special Purpose Rifle Upper Receiver is constructed using the highest quality materials. Built on our patented self-regulating short-stroke gas piston system, machined from materials that belong to the superalloy 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.
IC-SPR Uppers with LWRCI Monoforge™ 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. Gas-piston system can be accessed quickly by loosening two thumb screws and removing the top rail section.
Our IC SPR Upper uses LWRCI™ manufactured- NiCorr treated cold Hammer Forged spiral fluted barrel that is 20% lighter than unfluted barrels of the same diameter. The increased surface area reduces heat – speeds up cooling. Nickel-boron coated bolt carrier dellivers unparalleled wear resistance, corrosion resistance and permanent lubricity.
