Midwest Industries LR-308 High Profile 308 Combat Rail M-LOK Handguard - Aluminum Black

The Midwest Industries LR-308 High Profile 308 Combat Rail M-LOK Handguard is a free-float aluminum handguard engineered for DPMS-pattern .308 AR rifles that demand modularity and long-term durability. Built from 6061 aluminum with a hardcoat-anodized black finish, this handguard provides a lightweight, corrosion-resistant platform for mounting optics, lights, and other tactical accessories without adding unnecessary bulk to your rifle. If you're running a precision .308 build, a semi-custom hunting rifle, or a general-purpose rifle that needs room to grow, this combat-profile rail gives you the real estate and attachment flexibility to make it happen.

What sets this Midwest Industries handguard apart is the three sides of M-LOK slots—an industry-standard mounting interface that lets you add gear exactly where you need it. Five quick-detach sling socket points give you multiple anchor options for different carry styles, and the included five-slot rail provides immediate top-rail space for your primary optic or sight setup. Installation is straightforward: the 4140-steel barrel nut with 1 7/16-16 TPI threads torques down securely, and the included wrench makes the job easier. The anti-rotation block and steel torque plate ensure the handguard stays true under recoil and heavy use.

Midwest Industries designed this high-profile handguard to work with .210-inch tang-height receivers (DPMS High or Low pattern), available in 12.625-inch and 15-inch lengths. The 1.75-inch width and 2.187-inch height provide a confident, ergonomic grip profile without excessive weight penalty. The free-float design minimizes contact between the handguard and barrel, supporting consistent accuracy if you're stretching shots downrange.

Specifications

Frequently Asked Questions

Will this handguard fit my DPMS AR-10?

Yes, the Midwest Industries combat rail is designed for DPMS High and Low pattern receivers with a .210-inch tang height. Verify your receiver's tang height before ordering to ensure proper fit.

What's the difference between the 12.625-inch and 15-inch lengths?

Both lengths offer the same profile (1.75 inches wide, 2.187 inches tall) and feature set. Choose based on your barrel length and how much rail real estate you want for accessory mounting. Longer handguards provide more M-LOK slots and offer additional grip surface.

Is this a free-float handguard?

Yes. The free-float design means the handguard does not make contact with the barrel, which can improve accuracy consistency by eliminating variables that affect barrel whip and harmonics.

What's included in the box?

The handguard comes with a heat-treated 4140-steel barrel nut, a barrel nut wrench for installation, one five-slot Picatinny rail for top-mounted optics, and an aluminum anti-rotation block.
