The Midwest Industries CRM Combat Rail Handguard (brand part no. MI-CRM7) is a compact 7 inch M-LOK handguard built for short-barrel and close-quarters AR-15 configurations. A 4140 heat-treated barrel nut works alongside a patented, equally heat-treated torque plate to hold zero and clamp force under hard use, and a continuous 1913 Picatinny top rail keeps optic mounting consistent. One bolt-on M-LOK rail section ships with the handguard, and the whole assembly, including the barrel nut and wrench, installs as a one-piece free-float unit.
