The Yankee Hill Machine 10" M-LOK handguard is a lightweight rail system built for shooters who want modularity without unnecessary bulk. Whether you're running a precision rifle, a duty gun, or a lightweight hunting AR, the MR7 Assembly delivers a free-floating design that won't interfere with barrel harmonics, plus full M-LOK compatibility along the entire handguard length—including at every 45-degree position—so you can mount lights, grips, and accessories exactly where you need them.

YHM engineered the MR7 from 6061-T6 aluminum and finished it with hardcoat anodizing to military specifications or better, giving you a durable, matte black handguard that handles hard use without weighing down your rifle. The extended top rail features T-marked picatinny slots, letting you attach optics, magnifiers, or backup sights in a standard configuration.

This 10-inch handguard strikes the balance most AR builders want: it's among YHM's lightest options in its class, yet modular enough to support a complete accessories ecosystem without dead rail space. If you're building or upgrading an AR with a mid-length gas tube or prefer a compact, free-floating setup, the MR7 delivers the performance and flexibility to make that work.

Frequently Asked Questions

Is this M-LOK handguard compatible with my AR?

Yes—the Yankee Hill Machine MR7 uses standard M-LOK slots and mounts to any AR upper receiver with an M-LOK-compatible barrel nut. The 10-inch length pairs well with mid-length gas tube systems, though final fit depends on your specific rifle setup.

Can I mount a scope or red dot on top of this handguard?

Yes. The extended top rail features T-marked picatinny slots, so you can attach any standard picatinny-mounted optic, magnifier, or backup sight to the rail.

What makes a free-floating handguard better for accuracy?

A free-floating handguard doesn't contact the barrel, which means your barrel's natural vibration during firing isn't affected by pressure from the rail system. This helps preserve consistent accuracy by reducing variables that can shift your point of impact.

What accessories can I attach using the M-LOK slots?

M-LOK slots accept any M-LOK-compatible accessory—lights, grips, sling mounts, cable management, and more. The MR7's slots run the entire length of the handguard, even at every 45-degree angle, giving you maximum positioning options.
