Unity FAST Tactical Optic Riser Color:black Rear sight size: 45*25mmThe Unity Tactical FAST Riser was designed to bring red dot optics with built in lower 1 3 cowitness picatinny mounts in line with the heights of other Unity Tactical FAST products. This taller riser system enables picatinny compatible red dots to be mounted at a more comfortable height for users who need the ergonomics for use with equipment that makes traditional absolute and lower 1 3 cowitness height mounts inadequate for their needs.
