Midwest Industries High Combat Rail HD M-LOK Handguard Features The Midwest Industries High Combat Rail HD M-LOK Handguard is shaped and profiled for maximum rigidity which minimizes point of impact shift for night vision aiming devices mounted forward on the rail. A longer 4140 barrel nut provides added stability to the handguard s attachment point while machined heavy-duty anti-rotation tabs work alongside Midwest Industries patented torque plate system to ensure there is no forward movement under recoil or heavy use. Two steel anti-rotation QD sockets are strategically placed to maximize strength while minimizing gun roll during sling transitions. Together these engineering details make the handguard a dependable platform for AR10 shooters who need their optics and accessories to hold zero through demanding conditions. Constructed from Hard Coat Anodized 6061 Aluminum in a Black Anodized finish the handguard is fully dehorned and deburred for a clean snag-free feel in the hand. Seven sides of M-LOK slots give shooters nearly unlimited placement options for lights grips bipods and other accessories and the included 5-slot polymer M-LOK rail section adds a ready-to-use mounting point out of the box. At just 1.60 lbs and spanning 13.5 in length with a 1.85 outside diameter and 1.30 inside diameter the handguard adds minimal weight while maintaining a slim ergonomic profile. Backed by a lifetime warranty and made in the USA this handguard is built to be the last one an AR10 owner ever needs to buy.
