The Yankee Hill Machine FWS-I Thermal Optic Riser (Model YHM-225) is a precision-engineered mounting solution designed specifically for thermal optics. This high-quality riser elevates your thermal scope to the proper height, providing an optimal cheek weld and eye alignment when mounted on AR-15, AR-10, and other Picatinny rail-equipped firearms. Manufactured by Yankee Hill Machine, a trusted name in American-made firearm accessories, the FWS-I riser delivers the durability, strength, and accuracy demanded by serious shooters and professionals.
Optimized for Thermal Optics
Thermal optics often sit higher than traditional red dot sights or magnified scopes due to their larger objective lenses and housing designs. The YHM-225 FWS-I Thermal Optic Riser solves this issue by raising the optic to a comfortable and consistent height. This allows shooters to maintain a natural cheek weld on the stock while achieving proper eye relief and sight picture. Whether you’re using the riser for night hunting, tactical operations, or home defense, it ensures your thermal optic performs at its full potential without compromising ergonomics.
The FWS-I riser is machined from high-strength aluminum and features a robust Picatinny rail interface on both the top and bottom, allowing for secure mounting on standard Picatinny rails while providing a stable platform for your thermal optic.
