I only recently started playing airsoft, and got myself a GR16 Light Combo. I also purchased a red dot scope.
But I'm having trouble calibrating both the iron sight and the red dot sight. It seems to me that it alway hit about 2-3inches to the upper right. I tried adjusting the sight, but it seems to me that it won't go down or to the right far enough.
What are some tips in calibrating the sight? Is there a optimal distance which I should be standing to calibrate the sight?
Another concern is that I've heard it's rather easy to break the lens in a game. Is that true? If so, what can be done to minimize the risk?
Thanks in advance.
