I have a Dp G4 and it was working amazing until it was having major bolt stick. I had Sent it in for repair, Sadly it was My Solenoid but i had it replaced. The very next game i played after it was out of the shop, It would Shoot a very hot ball (310+fps) then the fps would DRASTICALLY drop to 130fps I have no clue what is going on. Hopefully its a quick fix because i cant go to the field until I have a working marker. Please Someone help me Out!!!
