Midwest Industries M-Series AR-15 Handguard, 14" 6061 Aluminum, Black Hard Coat Anodized

The Midwest Industries M-Series AR-15 handguard is a 14-inch free-float rail built for shooters who want a lightweight, modular setup without the bulk. Machined from 6061 aluminum and finished with hard coat anodization, this one-piece design gives you a slim 1.3-inch inner diameter that won't add unnecessary weight to your rifle while still providing plenty of real estate for mounting optics, lights, lasers, and other combat-proven accessories. Whether you're setting up a duty rifle, a competition build, or a hunting platform, the M-Series delivers the versatility serious AR owners expect.

M-LOK compatibility is woven throughout: seven mounting flats run the length of the rail, so you can place your gear exactly where you need it. A full-length Picatinny rail tops the 12 o'clock position for your primary optic mount or iron sights, while two integral QD sling sockets give you flexible carry options. The included 5-slot polymer M-LOK rail and barrel nut wrench get you started right out of the box—no hunting for parts or tools. Midwest Industries backed this handguard with a patented 4140 heat-treated torque plate to ensure rock-solid mounting integrity shot after shot.

Made in the USA, this is the kind of rail that rewards attention to detail: slim profile that lets you cowitness low-power optics, anti-rotation engineering so your setup stays put, and the durability to handle field use without flinch. If you're upgrading an AR upper or building from scratch, the M-Series M-LOK handguard is a no-nonsense choice that plays well with modern rifle platforms and accessories.

Frequently Asked Questions

Will this handguard fit my AR-15?

Yes, the M-Series M-LOK handguard is designed to fit standard AR-15 rifles. It uses a standard barrel nut interface and includes the wrench needed for installation.

What's the difference between M-LOK and Picatinny mounting?

This handguard offers both: M-LOK slots on the sides and bottom for a cleaner look with less snag, and a full-length Picatinny rail on top for a traditional mounting surface. This gives you flexibility to run whatever combination of accessories suits your rifle's role.

What comes in the box?

You get the handguard itself, a barrel nut wrench for installation, and a 5-slot polymer M-LOK rail to get you started with accessory mounting.

Is this handguard a free-float design?

Yes—the 1.3-inch slim diameter gives you a truly free-floating rail that doesn't contact the barrel, which helps maintain accuracy, especially at distance.
