ok this is a super durable tank, it comes with a good reg, and has a super fast recharge rate. I can get almost shoot a whole case with my 70/4500
a little heavy
hard to screw on and off your gun
tank can easily unscrew from the gauge on the tank
I reccomend this since i dont think there is anything else better out. It can keep up with any gun
Just as a side note - I've used an Ion before, and after looking at your list of ups, you probably still have the duckbill ASA on it. This is a stock SP ASA, and is not considered to be a great one at that. The ASA is likely the cause of the unscrewing problem. I'd suggest replacing it, because SP ASAs can be tank thread destroyers.
i agree with above. you need an on/off of ANY kind. you are trying to unscrew the tank under pressure (HP is 600-850 psi), it would be a toss-up wether you are unscrewing the fuel from your ion or the tank from the reg.
