HOPUP PROBLEM!

Feb 19, 2008 12:59am
This weekend I noticed I have to adjust my hopup after dumping 10-20 rounds. So I'm guessing something is loose or worn out. What is the cause of this and what do I need to do to fix this.
I like to run with scissors in my hand.

you must provide more information in order to get a qualified answer. Otherwise you will be stuck with this one...

Yeah that might help. This is a G&G UMP. I have to adjust the hopup every frekn time I finish shooting. My bbs shoot straight for the first 10-15 founds then I can see the bbs curve down after that.

Tighten the hop-up screws.

In fact when I shoot I can see the hopup switch move. How can I fix that?

did you check to see if your nub is still in? Sounds like something is missing to me.

Yeah the nub is still there. Should I buy a new one or just get a whole new hop bucking.
