Holosun HS503C Micro Solar Red Dot Sight – DISCONTINUED

Holosun 503C is a compact red dot sight with the option of a 2MOA dot only or a 2 MOA dot with a 65MOA circle reticle pattern. Employing new LED technology, the life time for one CR2032 battery can reach 2 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. The compact red dot sight may be installed on various firearms such as shotguns, pistols, rifles, air rifles and crossbows.
