Fast and very simple way to mount both a bright target illuminating light plus a fast aiming red laser to almost any scope with a 1" diameter body tube. Now you can illuminate your target under low light or zero light conditions while simultaneously directing a laser beam that will denote point of pellet strike. Easily mounts onto any 1" rifle scope with up to a 50mm diameter objective lens. Works for all small caliber rifles and all air rifles up to 1000 fps. Kit
