The 25-45 SHARPS cartridge was developed by SRC to maximize the performance of the Modern Sporting Rifle (MSR) platform. With a greater muzzle velocity and a harder hitting 65 and 87 grain bullet, its performance surpasses the .223 REM/5.56 NATO. The 25-45 SHARPS is compatible with the existing .223/5.56 bolt carrier group and magazines available for the MSR platform. Replacing the .223/5.56 chambered barrel is the only adjustment needed to take advantage of the 25-45 SHARPS superior ballistic capabilities, thus creating a flexible and versatile rifle with superior performance.
