The Millett Zoom Dot? 30mm reflex sight is a non-magnifying 1-to-1 ratio red dot illuminated aiming system that can be used in all lighting situations with one or both eyes open. The dot size can be zoomed down to 1 MOA for a long-range accurate shot, or up to 10 MOA for super-fast target acquisition under close quarters battle, by simply turning the knob.
Extensive testing on the S&W 500 mag and other high-impact weapons has proven that the ZOOM DOT is the most durable dot sight available. Its package size has been reduced, and a special mount is available for super-high-impact applications.
