Vanguard Demon Help
Just got my brand new 2012 demon and took it to the field yestarday to play a tournament.
Didn't made any change to the board settings and didn't relubed the bolt as it was well lubbed from factory.
At first I had some trouble getting the fps above 265 but I increased the dwell from 15ms to about 17.5ms and was able to get to the 275-280.
Played all day without any problems but at the end fo the day the gun stopped cycling and only makes a puff noise when I shoot it and vents air from the top grip / lower body area.
Since the gun is new to me can anyone guide me to what I need to inspect in order to solve the problem?
