Yankee Hill Machine Co Diamond Series Forearm Rifle 12.6" – AR-15 Free Float Handguard

The Yankee Hill Machine Co Diamond Series Forearm delivers a lightweight, free-floating platform that improves heat dissipation and enhances accuracy for AR-15 pattern rifles. The diamond-pattern ventilation cuts weight while providing effective barrel cooling during extended shooting sessions, and the full-length top rail maintains co-witness with your upper receiver for uninterrupted optic mounting.

Machined from 6061-T6 aluminum with a hard-anodized finish, this 12.6-inch handguard installs via a proprietary barrel nut system and requires removal of the standard delta ring assembly. M-LOK or KeyMod compatibility is not featured—accessory mounting relies on the included rail sections that attach at 3, 6, and 9 o'clock positions. Thread-on installation provides a secure, wobble-free lockup.
