FAST™ Riser – Optic Riser for Rapid Target Acquisition
The FAST™ Riser elevates the optical centerline to 2.26 inches (5.74 cm), enabling faster target acquisition — especially when wearing hearing protection, communication headsets, night vision devices, or gas masks. It promotes a more upright shooting posture that supports a neutral spine position, increasing comfort when operating with heavy gear such as helmets and plate carriers.
The mount is compatible with “lower 1/3” optics including the EOTECH EXPS, Leupold LCO, and Vortex UH-1.
