Ex. Chamber or Regulator?

[General Lee]

I have had my 98c for 2 years and have always used a Ex. chamber on it. Should I use a regulator, or what would be the reason for using one?

any advise would be a big help.

Well if you use a regulator, I suggest to use it in combination of an anti-siphon installed on your tank.

And the only reg. for CO2 use I recommend is the Palmer Stabilizer. The regulator will adjust the pressure of the CO2 gas going into the valve, and with it it will also make shot to shot consistency better (meaning less velocity spikes).
