Yankee Hill Machine Co Diamond Series 12.6in Rifle-Length AR-15 Free-Float Quad Rail Handguard YHM-9635-DX

Product Description

Upgrade your AR-15 with the Yankee Hill Machine Co Diamond Series Rifle-Length Forearm, a rugged free-float quad rail handguard built for secure accessory mounting and improved heat management. Its distinctive diamond-shaped heat vents promote airflow while reducing unnecessary weight, and the extended top rail is designed for a clean, gap-free installation. T-marked rail sections help you repeatably place optics and accessories, while the included anti-rotation hardware helps keep the handguard locked in place under hard use. Constructed from 6061-T6 aluminum with a mil-spec hardcoat anodized matte black finish, this forearm is engineered for durability and long-term performance.
