automag build questions

[wrongbloke]

Im toying with the idea of building my tac-1 out for a limited paint format game that my friends and I have been kicking around as an idea. Its just on the drawing board in my head for now so to speak, really more of a "wouldnt it be cool..." so im not married to the idea, no offense taken if the idea is undoable, but just dont be jerk about it lol

my idea is to make a 10 round springfeed adapter for my tac and run it off of a 3.5oz co2 or a 13/3000. Im not looking for crazy efficiency, just enough to maybe shoot 4-5 full springfeeds before having to refill my tank. I had a few questions:

1. I know mags are kinda gas hogs, how many shots could one get off of a 13/3000, what about a 3.5oz co2? if it depends on the valve im thinking of either a classic valve or an X-valve (I know not to run co2 thru an x valve btw lol)

2. What is the most efficient valve out there?

3. What kind of mods can be done to make a valve more efficient, or is there someone here on the forum who does them custom or has done this for themsleves before? how efficient are we talking here? is it even worth it?

thanks

My classic valved pump mag does 130-140 good shots off of my 13" tank. So 4-5 full spring feed shouldn't be a problem. I think you could do 12-13 easy.
