wanting to go nitro

[Never Trust a Monkey]

I've been running co2 through my mag and would like to go nitro if I found a good deal on a tank. But i have some questions. I have Air America's black ice reg. on it and the reg. says that the max psi's are 850. And I want to know if that's the maximum psi's that it will put out, or if that's the max that u can put into it without blowing it up? And is this reg. good enough to run nitro? Or would i be better off just going straight from the tank to the gun? What is the best thing to do?
Thanks and any help would be greatly apprectiated

All you really need with nitro is to run it to the valve, adding another reg is a bit of a waste, seeing as you are already regulating the pressure twice as it is, seeing as the tank reg regulates the pressure, then the valve in the gun regulates it down to operating pressure. Triple Regging your gas isnt really required, and could potentially cause shootdown. If you don'nt know already, 'mag valves should have about 700 - 800 PSI going into the valve.
