There is no info in the owner's manual as to how to use CO2. Can you just invert a paintball tank with a valve and hose and connect it to the existing foster fitting? Has anyone tried CO2?
You need to cool the reservoir on the gun to get a complete fill. You can do that a number of ways but shooting a few blanks on a partial fill is the easiest. Then you just do another fill and it will be as close to safely full as you are going to get. Check the guage it will not read like with air since CO2 will hold the same PSI until the cylinder on the gun is almost empty (temp = Pressure on a CO2 fill). also if your paintball tank has a siffon tube you don't need to turn it upsidedown.
