The Midwest Industries Combat M-LOK Handguard (brand part number MI-CRM4.5) is a 4.5-inch free-float rail built from 6061 aluminum with a continuous 1913 Picatinny top rail and M-LOK slots wrapping the remaining sides for accessory mounting. Midwest Industries finishes the handguard in black hardcoat anodizing and uses a 4140 heat-treated barrel nut paired with a matching heat-treated torque plate, so the rail stays true under recoil rather than shifting over time. Two integral anti-rotation QD sling sockets are built into the handguard itself, and every edge is fully dehorned and deburred for comfortable, snag-free handling. It ships complete with the barrel nut, installation wrench, and a 5-slot polymer M-LOK rail section, and the whole handguard is made in the USA.
