I just bought a Ninja 50 45 brand new so it has the stock ninja reg, i screwed it into my old bt combat just to take a few shots without setting up my other marker. I have the electronic trigger for it and i can only take about 4 shots fast before it loses pressure and the bolt doesnt come back?

The Reg is a low pressure reg the BT requires 600psi up to 850psi.
