The HS503CU Circle Dot is a compact red dot sight offering a 2 MOA dot or a 2 MOA dot with a 65 MOA circle reticle pattern. Employing new LED technology, the life time for one CR2032 battery can reach two years if left on constantly. However, the solar technology and automatic brightness features work together to extend the battery life dramatically beyond that for the average shooter. Featuring a housing design that shrouds the windage and elevation turrets on two sides. Perfect for shotguns, pistols, rifles, air rifles, and crossbows.
