Mi 308 Low Combat Rail Hd M-Lok Handguard 15
$279.95
The Midwest Industries Mi 308 Low Combat Rail M-LOK handguard is a purpose-built free-float solution for serious AR-10 builds where rock-solid rigidity and zero shift matter. Built to military specs with a focus on durability over compromise, this 15-inch handguard uses a longer 4140 barrel nut and machined anti-rotation tabs to lock everything in place—critical for long-range precision and NV aiming devices that demand consistent zero.
The handguard's combat-focused design minimizes the points where movement can creep in. Two steel anti-rotation QD sockets are positioned to reduce gun roll and maximize strength under use. Midwest Industries' patented torque plate prevents forward handguard movement, a detail that separates combat-grade rails from generic aluminum tubes. The body is 6061 T6 hardcoat anodized aluminum, fully dehorned and deburred for a smooth feel without sacrificing strength or weight.
M-LOK slots run across seven sides of the handguard, giving you mounting flexibility for lights, lasers, bipods, and tactical accessories without committing to a single rail system. The 5-slot polymer M-LOK rail is included. At 1.750" outside diameter and 1.250" inside diameter, it's a low-profile fit that doesn't add unnecessary bulk to your setup. This is made-in-USA gear built to last, backed by Midwest Industries' limited lifetime warranty.

Frequently Asked Questions
What platform is this handguard designed for?
The Mi 308 is engineered for AR-10 rifles chambered in .308 or similar large-frame AR platforms. The longer 4140 barrel nut and combat-profile design are optimized for full-size AR-10 uppers.
Does it work with night vision aiming devices?
Yes. The handguard's rigid construction and anti-rotation features are specifically designed to minimize point-of-impact shift when mounting NV devices, so your zero stays true under magnification and thermal sight use.
What's included in the box?
The handguard comes with a 5-slot polymer M-LOK rail already included. You'll need to source your own barrel nut wrench and appropriate fasteners if you don't already have them on hand.
How much M-LOK real estate does this rail provide?
M-LOK slots run across seven sides of the handguard, giving you extensive mounting options for lights, lasers, bipods, and other tactical gear without forcing you into an all-in-one rail solution.
