Hi Guys, I was wondering if any body can offer some advice on this. I have just got hold of an early 90's Phantom & was hoping to trick it up a bit. It's currently set up with 12gram co2 but I wanted to change it to bottle, only to find out my local site doesn't have a co2 filling station. Do I have to stick to the 12grams or can I run it with compressed air? Sorry if I'm being a bit thick but I have been out of the game for a very very long time. Any ideas will be gratefully received.
