If the red and green dot sight could not work properly, please have a check:
1. Check the batteries to make sure whether they are dead.
2. If the batteries are fine, please take out the batteries from the battery housing, and correct the spring. Then put the batteries again. [Mind: put the batteries slightly, or the spring will be slanting, which easily make the dot sight cease operation.]
3. If the problem still could not be solved, please contact us directly. We will try our best to help you.
