This tank is pretty good, I use it on my tribal twister 2.2, the thing is i got one of the bad ones so i had to contact aci and they told what was wrong and sent me parts to fix it. now its good again. i also bought a 32 degreez 68ci psi 4500
i put it at 850psi on my tribal as well and i found out that it sucks air like crazy!
also i found out that rps were a reason as well. I used Powerball and was shooting over limit. so paint is also a concern.
anyways this tank is great dual regs and guages this tanks is great
only that i got a bad tank and had to get free parts from aci
i paid somewhat like 230 for it , its working great so i think so
i would recemend it
