OPT-Crew Doctor type mini dot sight.
The red dot lights up with a CR2032 button battery.
To replace the battery, remove the two hexagonal screws on the top, separate the pedestal and main unit, and insert the battery into the back of the main unit.

(About handling)
Normally, the mini red sight turns on with the front photosensitive sensor when the resin cover is removed, and turns off when the cover is put on, but the sensitivity may be dull and the light may continue to emit light, although the brightness is reduced.
We recommend removing the battery when not in use.
