The Yankee Hill Machine MR7 15-Inch M-LOK Handguard (brand part number YHM-5318) is one of YHM’s lightest handguards to date, built to keep weight off the front end of an AR-15 without giving up mounting real estate. M-LOK slots run the full 15-inch length of the handguard, including at every 45-degree position around the circumference, so accessories can be positioned exactly where a shooter wants them. A T-marked extended top rail ties the handguard into the upper receiver’s rail for a continuous sight line. Whether the build is a lightweight patrol carbine or a competition rifle that needs room for a light, sling mount, and grip all at once, the MR7 gives builders the flexibility to configure accessories around the whole handguard.
