KWA MP9 Hop up issue
 

Hi all,

so the problem is pretty simple, my hop-up is set to zero and my bbs are curving like it's at the maximum...

I have tried to turn it on the otherside but it was worse, so hop up seems to work but it has an effect also when it supposed to be off.

Does anyone has this issue ? or a solution? Before i open everything :)

Thks Guys!

I am having a similar issue with my hop on my KWA MP7, and if I'm not mistaken its a sign that the hop-up rubber has become swollen due excess oil being adsorbed into it (apparently these things are like sponges for any type of oil) 2 thinks you can do is take it all apart, and replace the rubber, or take it all apart soak it water and small qty of mild soap, let it dry then put it all back together again.

That's excatly what i was reading about the problem, did-it solve the problem on your MP7?
I'll try it on my side! Thks!
