The Holosun HS503GU red dot sight uses a circle dot reticle. The battery is in a round, screw on turret on the outside of the optic. However, with the technology in this light you will rarely have to change it. One CR2032 battery can last 2 years if left on constantly. But, with the automatic on/off feature which uses motion your battery will last much longer than 2 years. It has an unlimited field of view and unlimited eye relief.
