Ok the rapid firing intimated that it was electro...if it's ripping off then it's definately a c02 supply issue,as with site tippmans when the c02 gets low they rip off for some reason.Thanks, my marker is mechanical... It is semi auto, nothing else. I've totally cleaned every single part of the marker. I'm thinking about just sending it back and getting something different.
Thanks for your help
I'm sure someone else can tell you why.
