I am thinking about buying a dv8 and called them atleast 5 times and no response so im asking the exsperts on pbnation. ih ave a 20 oz and a pe 72/3000 but that thing is way over 800 so my question is does the built in regulator vent higher presure n2 or is it smarter to stick with my anti siphoned co2.
I think you are a bit confused over the PSI. Although your HPA tank can hold up to 3000 PSI, the output (actual pressure sent to marker) is only 700-750 PSI, which IIRC is roughly the same as a CO2 tank. Soooo, an Epic can run on either the HPA or CO2 tank without a problem.
But remember, Regular CO2 < Anti-siphoned CO2 < HPA.
