Ok, this is what i have done so far. there is the usual power mods, too.

The hole on the side of the gun is from a previous failed atempt to add a line for the big co2. I'll get a cap to cover it later. But its good for hearing leaks

The scope on the gun is just crap, its a 8 dollar wal-mart special.

It was not hard at all to convert to the big co2. I think it would cost about 10bucks to do. I dont really know how much all the fittings and lines cost since i already had them. They charge me a buck to get the tank filled

Hey, looking good. If anyone wants to know, converting to CA (constant air) would not cost alot at all to do. You could pick up a macroline kit, or a steel braid hose for well under $10, a co2 tank can be had for under $10 also, and the ASA (air source adapter) could be had for $5. I'm assuming you just used a 1/8 npt tap on the peircing assembly or was it already threaded?

yes, i tapped it with the NPT tap.

Hello, I have a couple of questions about your current set up. I would like to get a list of all the fittings and adaptors you used. and do you have to have a regulator on the tank or no?,is there a on and off switch?(because I dont want to leave it compresed),how did you get the cable comming from the tank to hook up with the place where the cartrages usaly go?, and how do you refill it straped on the gun like that. I am wanting to go bulk withought spending 60 bucks on a kit. and how big of a tank can you have mounted on the gun withought blowing the internal value. Someone please answer my questions.
