The FAST™ Optic Riser elevates most lower 1/3 co-witness rail-mounted optics—such as the EOTech® EXPS Series—to a 2.26″ optical centerline for improved ergonomics and faster target acquisition.
It comes standard with a two cross-bolt rail clamp and is compatible with the FAST™ QD lever for quick-detach capability. The riser also integrates seamlessly with all FAST™ FTC magnifier mounts.
