PROBLEM TO BE SOLVED: To provide a large caliber dot sight device which is attached to and detached from the upper end of a mechanical part of a heavy machine gun, enables binocular vision and enables rapid and accurate sighting by minimizing parallax.SOLUTION: A dot sight device comprises a protection window formed at the front, a reflection mirror formed behind the protection window, an LED irradiating the reflection mirror with light, an illumination part situated at the tip of the LED and having a light projection reticle which projects the light emitted from the LED to form a dot image, and a fixed grille formed on a lower part. The dot sight device is attached to and detached from a mount for a heavy machine gun by the fixed grille, and a width X of the reflection mirror and a distance Y between both eyes of a user satisfy a relationship of X>Y. |
