Empire 56 CI Tanks?

I was looking at buying one of these, but I am unsure of what output pressure the stock reg has. Is anybody familiar, or know if there is a visual way to check?

Looks like standard pure energy regs (though they call it a reactor 4 reg). Standard output 800, ment to match co2. Maybe 850 but that maybe just ninjas standard output.
