Mi 308 Low Combat Rail Hd M-Lok Handguard 13.5
The Midwest Industries Mi 308 Low Combat Rail M-Lok handguard is a 13.5-inch free-float rail system built for shooters who demand a rock-solid platform for precision rifles and duty weapons. Designed around a low-profile footprint, this handguard minimizes bulk while delivering the rigidity and control serious marksmen need—whether you're running a magnified optic, night vision, or a tricked-out modular setup.
Built from 6061 aluminum with hardcoat anodization, the Mi 308 is engineered to handle hard use without losing zero. The design includes steel anti-rotation tabs and Midwest's patented torque plate to lock the handguard solid to your upper receiver, eliminating creep and point-of-impact shift—critical when you've dialed in your zero for distance or NV work. A longer 4140 barrel nut adds stiffness where it counts, and all edges are fully dehorned and deburred for comfortable handling and snag-free manipulation.
The M-Lok system gives you seven sides of accessory mounting real estate, letting you attach lights, slings, grips, and foregrips exactly where you need them. The included 5-slot polymer M-Lok rail gets you started; the 1.750" outer diameter and 1.250" inner diameter keep the platform trim without sacrificing capability. Made in the USA with a limited lifetime warranty backing the build quality.
