The HS503GU is a red dot sight that features a 65 MOA circle with a 2 MOA dot reticle. The housing design shrouds the windage and elevation turrets on two sides. Employing LED technology, the life time for one CR2032 battery can reach 2 years if left on constantly. However, the motion based automatic on and off feature extends the battery life dramatically beyond that for the average shooter.
