Yankee Hill Machine Diamond Series AR-15 7.29" Quad Rail Free Float Handguard - Carbine Length

The Yankee Hill Machine Diamond Series carbine-length handguard gives AR-15 builders a rugged, lightweight free-float platform for optics, lights, lasers, and foregrips. Machined from 6061-T6 aluminum and finished in Mil-Spec hardcoat anodized matte black, it is purpose-built for carbine-length gas systems and installs using the included barrel nut, jam nut, two anti-rotation screws, and forearm tube.

Measuring 7.29" overall with an 1.75" inner diameter, the Diamond Series forearm runs a continuous quad rail at the 12, 3, 6, and 9 o'clock positions with aggressive diamond-shaped heat vents cut through the sides and bottom to promote cooling and shed weight. An extended top rail bridges the upper receiver for a gap-free mounting surface, while "T"-marked slots let the user record and repeat accessory placement. The complete assembly weighs 12.5 oz.

Designed and Made in the USA by Yankee Hill Machine, the YHM-9630-DX delivers the fit, finish, and rail real estate of higher-end handguards at a working-class price point, and is fully compatible with standard AR-15 uppers.
