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 Millett Reflex Sight Zoom Dot ZM00001, Solid State, Waterproof, Matte is the most durable dot sight available. Its package size has been reduced, and a special mount is available for super-high-impact applications. The Millett Zoom Dot automatically adjusts dot brightness to match ambient light conditions, giving the warfighter a bright dot inside a dim building or outside on a snow covered field.
