Midwest Industries High Combat Rail HD M-LOK Handguard Features The Midwest Industries High Combat Rail is shaped and profiled for maximum rigidity under extreme use an important factor on AR-10 platform rifles chambered in .308 Win where recoil and barrel harmonics are more pronounced than on smaller calibers. Minimal point of impact shift for night vision aiming devices makes this handguard a strong choice for shooters running NV optics in low light conditions. A longer 4140 steel barrel nut provides additional stability to the handguard reducing flex that can affect accuracy over repeated strings of fire. Machined heavy duty anti-rotation tabs work alongside the patented Midwest Industries torque plate system to eliminate forward movement keeping the handguard locked solidly in place. Two steel anti-rotation QD sockets are strategically placed to maximize strength while minimizing gun roll when a sling is attached improving handling during movement and transitions. The handguard body is constructed from hard coat anodized 6061 aluminum finished in Black and fully dehorned and deburred for a clean snag-free profile. A 5-slot polymer M-LOK rail is included and the handguard offers M-LOK attachment points across seven sides for mounting lights grips bipods and other accessories. Measuring 15 inches long with a 1.30 inch inside diameter and 1.85 inch outside diameter and backed by a lifetime warranty this Midwest Industries handguard is proudly made in the USA for AR-10 shooters who demand a rock-solid precision-fit rail system.
