How to adjust the velocity?

[cloud113]

I was looking for a thread where it showed a picture of where you adjust the velocity, but I can't find any on my search. I couldn't use my gun (Automag RT ULE Custom w/ x-valve, intelliframe, and ultralite) today at the paintball place because it wouldn't go below 300 FPS . I was wondering if anyone could post a picture and like maybe draw a circle around the place you adjust the velocity. Thanks a bunch.

In the back part of the valve. withc is black there is a silver circle potruding out of the back. in the center of the circle there is an allen key hole. turn the whole silver part counter clockwise

Ok I see the silver thing sticking out of the x-valve, but when I try to turn the allen wrench I hear this cracking noise and I can't turn it counter clockwise anymore. What's the problem?
