The Midwest Industries Lightweight Combat Rail Free Float M-LOK Handguard for AR-15 is a precision-engineered free float system built for shooters who want a slim, rugged platform without the weight penalty. If you're running a modern AR-15 and demand tight tolerances, reliable accessory mounting, and a handguard that won't shift or ring, this combat rail delivers. The one-piece free float design isolates your barrel from external pressures, which matters for accuracy whether you're dialing in at the range or building a duty rifle.
Construction is where this handguard earns its reputation. Midwest Industries machines the body from 6061 aluminum and applies Type 3 hard coat anodizing—the same finish spec you'll find on high-end optics and tactical gear. A patented 4140 heat-treated torque plate engineered into the design means installation is straightforward and repeatable, and the included barrel nut wrench takes the guesswork out of setup. The profile is genuinely slim: 1.5" outside diameter and 1.3" inside keep the handguard compact without sacrificing mounting real estate.
M-LOK slots run all four sides, so you've got full 360-degree rail flexibility for lights, bipods, grips, and slings. Two integral anti-rotation QD sling sockets are built in, eliminating the need to hunt down add-on hardware. The top features a full MIL-STD 1913 Picatinny rail for optics, backup sights, or offset accessories. All edges are fully dehorned and deburred—no sharp corners to snag gear or hands. Weight ranges from 7.6 oz on the 10.5" version up to 9.7 oz on the 15" length, so you're not sacrificing handling or balance. Everything ships with the barrel nut, screws, and wrench included. Midwest Industries manufactures this handguard in the USA and backs it with a lifetime warranty. Note: this handguard is not compatible with AR-15 gas piston platforms.
