G&P Aimpoint

[Boyso]

Alright I have this aimpoint for a while now but never gamed it.

I tried adjusting it yesterday and even by unscrewing the small screw on the right to the max, the dot is till about 1 cm away from the middle. I see the dot moving, just not far enough.

What am I doing wrong here?

Also!

I don't know if it's a battery issue, but the red dot works fine, but the green dot just stopped functioning. It just won't appear.
