Yankee Hill Machine YHM-5343DX Black Diamond M-LOK Handguard AR-15 12.6" Rifle Length

The Yankee Hill Machine YHM-5343DX Black Diamond is a slim, lightweight free-float M-LOK handguard built for the AR-15 rifle-length platform. Machined from 6061-T6 aluminum and finished in a mil-spec hard-coat anodized matte black, this handguard delivers the rigidity and durability expected from YHM's accessory line while keeping overall weight to a minimum.

At 12.6 inches long, the Black Diamond is purpose-built for rifle-length gas systems and provides generous rail real estate for accessories. M-LOK accessory mounting slots are positioned at the 3, 6, and 9 o'clock positions, allowing direct attachment of lights, lasers, foregrips, bipods, and other M-LOK-compatible accessories. The slim profile and 1.75" inner diameter deliver a comfortable grip surface and ample clearance around most barrels and suppressors.

Tipping the scales at just 12.44 oz, the YHM-5343DX adds functional length and modularity to your AR-15 build without overburdening the front end. Made in the USA and backed by YHM's reputation for quality American manufacturing, this is a straightforward, no-nonsense upgrade for builders running a rifle-length upper or looking for a lighter, slimmer alternative to traditional quad-rail designs.
