Hi guys, I've been having trouble with my 2012 demon since I got it out of the box. Actually my team won 5 of them at a MAPL event and 3 aren't working. And it took three months to get them.
Leak comes from inside the frame by the trigger.

I have replaced all drive train/bolt orings. Checked all the solenoid O-rings (doesn't come with replacements)
When I adjust velocity it only shoots 240 before it leaks.

I will not order spare parts, address vanguard or a vanguard service center considering the horrible service I've had with them so far

So your opinions/help is much appreciated

You need to try to reset the QEV diaphragms, or replace them.
