Powered by CR2032 battery
Eliminates the need to line up front and rear sights, allowing you to aim faster and get shots off sooner. The Fastfire II mounts low and weighs a mere 1.6 oz. The metal housing is durable enough to perform on the slides of high-power semi-automatics, slug guns, shotguns, and high-power rifles. The lenses are precision-ground and polished to exacting geometries to virtually eliminate parallax. The dot brightness automatically adjusts with the natural lighting. Windage and elevation adjustments are lockable. Powered by a CR2032 battery that can supply up to five years of life.
