The Midwest Industries MI HANDGUARD CRM HD 308 M-LOK is engineered for maximum rigidity and extreme use, delivering exceptional stability for AR platforms with minimal point of impact shift on NV aiming devices. Built around a 4140 barrel nut for enhanced stability and featuring machined heavy-duty anti-rotation tabs, this Combat Rail HD M-LOK handguard uses the MI patented torque plate to prevent any forward movement, while two steel anti-rotation QD sockets provide maximum strength and are positioned to minimize gun roll. Crafted from 6061 hardcoat anodized aluminum and fully dehorned and deburred for a clean profile, it includes a 5-slot polymer M-LOK rail and access to the Seven Sides of M-LOK for versatile accessory placement. With an outside diameter of 1.85 inches and an inside diameter of 1.30 inches, the CRM HD 308 M-LOK embodies balanced ergonomics and rugged reliability, proudly made in the USA and backed by a lifetime warranty. Its AR compatibility, durable construction, and thoughtful hardware placement make it an ideal choice for precision rifles and tactical setups where rigidity, repeatable accuracy, and secure attachment of optics and accessories matter most.
