Specs

• Inlet pressure of ~800 PSI for CO2 cartridges/tanks
• Outlet pressure to be determined, but starting at 150 PSI
• The smaller the better in terms of wearability

Options

1. Paintball gun regulators
   1. Inlet pressure gauge is 1000 - 4500 PSI
   2. Ohh! The gauge is only inlet, so it not actually a regulator! Some do allow outlet adjustement.
   3. Very small
   4. Unknown flow coefficients
   5. Unknown outlet pressure
   6. Not too expensive
