Midwest Industries MIULW105 Ultralight AR-15 10.50" Picatinny/M-LOK Handguard - Black Anodized Aluminum/Polymer

The Midwest Industries MIULW105 Ultralight AR-15 handguard is built for shooters who refuse to sacrifice control or modularity for weight savings. At just 6.8 ounces, this 10.5-inch handguard delivers the kind of featherweight performance that matters on long range days, tactical courses, or any rifle where ounces add up to fatigue. Constructed from rugged 6061 aluminum with Type 3 hard coat anodizing, it's tough enough for hard use without the bulk.

The handguard integrates both MIL-STD 1913 Picatinny rail on top and M-Lok slots on all four sides, giving you genuine flexibility in how you mount optics, lights, and accessories. The slim profile—1.5 inches outside diameter, 1.3 inches inside—keeps your grip close to bore axis for better control, while the fully dehorned and deburred design won't tear up your hands or gear. Two integral anti-rotation QD sling sockets are built in, so you can run your rifle slung without extra hardware.

Installation is straightforward thanks to the included patented 4140 heat-treated torque plate and barrel nut wrench; the torque plate simplifies the process and ensures proper seating. Midwest Industries includes a 5-slot polymer M-Lok rail and a titanium barrel nut with titanium screws, combining strength with minimal weight. A Bosque note: this handguard is not compatible with gas piston AR systems—it's designed for direct impingement rifles.

Made in the USA, the MIULW105 backs its build quality with Midwest Industries' lifetime warranty. If you're running a lightweight or precision build and want a handguard that won't slow you down, this one earns its place on your rifle.
