Running an anit-siphon tank and an expansion chamber are on my list of things to do to my A-5. Its a pretty cheap and easy way to keep liquid out of the valve, which is where you will get problems with consistency on a CO2 setup. Other than consistency though, Tippmans run great on CO2. Liquid in the valve wont cause as much trouble in a tippmann as with any of the higher end guns.
