Midwest Industries MINF135 Night Fighter 13.50" M-LOK Handguard - Black Hardcoat Anodized Aluminum with Barrel Wrench, Nut, & 5 Slot Rail

The Midwest Industries Night Fighter 13.50" M-LOK Handguard is purpose-built for AR platform shooters who run mounted lights, lasers, or designators in low-light work. Unlike traditional mil-spec handguards that can shift your point of impact when running laser systems like the ATPIAL, DBAL, or NGAL, the Night Fighter's rigid construction and heat-treated steel barrel nut hold zero reliably even under the mechanical stresses of mounted optics and pressure devices. At 13.5 inches, it gives you ample real estate for accessory mounting while keeping the overall profile slim and controllable.

Built around a 2.250" long 4140 steel barrel nut and engineered to minimize handguard flex, the Night Fighter delivers the kind of mechanical stability that matters when your carbine has to perform. The 6061 aluminum body is hard-coat anodized and fully dehorned, so you won't snag gloves or skin during weapon manipulations. Seven sides of M-LOK slots—plus a continuous mil-spec Picatinny rail on top—give you modular options for lights, pressure switches, RIS mounts, or barrier stops without the need for proprietary rails.

Everything you need to install it comes in the box: the barrel nut, torque wrench, and a 5-slot polymer M-LOK rail. Installation is straightforward on standard forged upper receivers; just verify compatibility if you're running a billet upper. The Night Fighter tips the scale at 14.1 ounces and is made entirely in the USA with a lifetime warranty backing your investment.

Frequently Asked Questions

Is the Night Fighter compatible with my AR upper receiver?

The Night Fighter 13.50" handguard is compatible with standard forged upper receivers.

Will this handguard work with my laser designator or mounted light?

Yes. The Night Fighter is specifically designed to reduce point-of-impact shift when running popular laser systems like the ATPIAL, DBAL, and NGAL. Its rigid construction and heat-treated steel barrel nut are engineered to hold zero with mounted pressure devices and optics. The continuous top Picatinny rail and seven sides of M-LOK slots give you flexible mounting options for lights, lasers, pressure switches, and other accessories.
