I currently have Apex sights on my antiquated Bear bow and I can't figure out how to adjust it left or right.

Right now the arrows are going just a wee-bit to the right of the pin, so if I aim just slightly to the left of my intended target I can hit in the spot where I want the arrow to go (most of the time lol). So how do I move my sights to the right?

Also, my 20 pin is really only effective up to 15 yards; at 20 yards I have to use what would essentially be my 30 pin. So if I want my 20 pin to actually be at 20, do I move my sights up? I just can't seem to figure it out.

Thanks for any help in advance.
