Holosun HS503GU Red Dot Circle Dot Reticle

Holosun HS503GU Red Dot Circle Dot Reticle

The Holosun HS503GU is a Red Dot shooting scope sight that features the circle dot reticle. The “G” in this night optic signifies that the battery is in a round, screw-on turret on the outside of the optic. “U” signifies a housing design that shrouds the windage and elevation turrets on the two sides of the shooting scope. Employing new LED technology, the lifetime for one CR2032 battery of this night optic 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. Shop this shooting scope online today!
