Reply To: My Ninja 68/4500



Your Ninja tank will handle more fill pressure but (and I don't know the terminology either, on their regs) the reg may be set for paintball use so think 800psi/55ish bar output.(CO2 pressures).  You can fill that gun to 2900psi/200 bar.

I wish I could help you figure out the reg's output pressure but I've never touched a ninja reg.

On the flip side, most of us don't use tanks with regulated output pressure. Tanks with good gauges will tell you where you are in the fill process and hopefully the guns gauge is good enough to confirm, go really slow and you just close the valve when the pressure shows right.. Tank regulators are common for tethered shooting, but even that's a small (but growing) %.
