need HPA help!!!

[stompdown]

I have a 68 automag classic and a defiant. I'm not sure if I need a low pressure or high pressure tank. Does anyone know what the classic 68 uses as far as low or high pressure?? Also, can someone recommend a reliable tank possibly with adjustable high/low pressure? I'm looking to purchase a HPA tank and need some help. Thanks

something like a Myth reg would be perfect :D , though pricey...any preset crossfire or similar should do.

the classic needs a good 600 min, the defiant will take anything 600-800 psi with ease...

the defiant should have a secondary regulator. (forgrip thingy)

with that said get a high pressure tank as the low pressure tanks are prety much useless. you need a HIGH pressure out put around 650+ at least for the mag. and with the high pressure of the tank the secondary regulator of the defiant will lower it down to what it is needed
