Yankee Hill Machine Co Gas Block Riser – Scope Mount Adapter

The Yankee Hill Machine Co Gas Block Riser is a precision-machined adapter that elevates optics mounted on low-profile or standard gas blocks. Designed for AR-15 and AR-10 platforms where the gas block serves as a secondary mounting point, this riser provides the necessary height to achieve proper sight alignment with co-witnessed iron sights or red dot optics. It's particularly useful on rifles with non-standard barrel configurations or when converting from a front sight base to a low-profile gas block setup.

Constructed from aircraft-grade aluminum with a mil-spec hard coat anodized finish, this riser clamps securely to most standard gas blocks with a Picatinny rail section. The low-profile design adds minimal weight while maintaining a solid, repeatable zero. Installation requires proper torque specifications to ensure secure mounting without damaging the gas block. Not intended as a primary optic mount—designed for backup iron sights or forward red dot positioning only.
