Yankee Hill Machine Co MR7 M-Lok HandGuard, Fits AR-15, 12.25" Rifle Lenght, 14.8 Oz,YHM-5320 Includes All Tools, Parts, & Instructions

The Yankee Hill Machine Co MR7 M-Lok AR-15 handguard is a lightweight free-floating rail built for shooters who want to run a clean, minimal setup without sacrificing modularity. At 14.8 ounces, it's engineered to be one of YHM's lightest handguards to date—a significant advantage if you're building a precision rifle, a fast-handling hunting gun, or an agile patrol carbine. The M-Lok mounting platform lets you attach accessories wherever you need them, including at every 45-degree position along the rail, so you can customize your firearm's ergonomics without unnecessary weight.

Built from 6061-T6 aluminum and hardcoat anodized to military spec, the MR7 delivers the rugged durability YHM is known for. The extended top rail carries a T-marked Picatinny section, giving you a proven optics platform while maintaining the lightweight profile that makes this handguard stand out. The free-floating design helps maintain consistent accuracy by decoupling the rail from the barrel, a feature competitive shooters and hunters alike appreciate.

The complete kit includes everything you need to install it: the barrel nut, jamb nut, anti-rotation screws, and instructions. No hunting through your spare parts bin or making a second trip to the shop—just grab this, bolt it on, and start building.
