I am considering Saving for a Pressurized CO2 system, and i have some questions. Im thinking about Red Sea Paintball Cylinder Style Regulator KIT, Does anyone have this? How long do the Paint Ball Cylinders last if your running say 30ppm co2?How Long would a 2.5 lb Cylinder last? How long does a 5lb Cylinder last if i get a unit for standard CO2 tanks? How long does a 20LB cylinder last? Does anyone know of a reasonably priced kit for the 2.5,5,and 20lb Cylinders? it would be a Standard Cylinder.
