I've tried it on a paintball system and it didn't work too well, it was very hard to get any consistency with the bubble count but that may have been due to the high pressure. With a proper regulator it may be a little better, but it will never have a very fine resolution, meaning it will always be tough to adjust.
If it's your first try at pressurized CO2, I'd recommend something better, there are some really nice Parker H3L on ebay (item #140910145626, but I think the listing JUST ended, will probably come up again though) for $25 that are a real forum boner right now. Great valve that normally sells for $260+
