Okay, this is very frustrating. Ever since I got my Tippmann a5 it hasn't worked properly. I tried putting on a Response Trigger and that is where I started having issues. I sent my gun in and it comes back with the same problem, burping. Get this: I shoot without paintballs and my gun works fine, but when I have paintballs in my cyclone, it goes nuts and practically goes full auto until I re-cock it. What the **** is going on? The only upgrades I have is a Regulator, Softer panals and a drop forward. At first my cyclone wasn't feeding, so I turned up the gun. Now it's going berserk again. Anyone got any tips on how to fix it?
