Rapid Fire 2000, Or Airtech 20?

Anyway, i had the parts of a rapid fire 20 and an airtech 2000 just lying around. But i was dissapointed in how much you had to pump the airtech to get it fully pressurized. So i tooke the RF20 pump, and attached it to the AT2k air chamber. I then sawed off the AT pump barrel and trigger, and put all the parts into various sizes of pvc tubing, all duct taped together. The result: a one pump per shot gun, mini-rifle sized, and allthough i haven't tested it, i think the range is about 50-60 feet on one pump, 70-90 on two (you can pump it twice...but its a bugger the second time). I'll have pictures if i ever get a digital camera. I want to add a clip system to the barrel or something, i'm not sure. Oh yeah, it's brass barreled by the way.

How did your pump break. Eight pumps is 2-3 times how many pumps it should need. I just do three pumps.Yeah, i know, but i had neither case. And my AT2k pump was broken. Yeah, it took like 8 with my AT pump.
Nerf on!

What I mean is take out the rubber air bladder and the piston valve that roatates fires the gun, but leave in the splitter. Attach the pump of the RF20 to the AT2K right at the spliter. This would give you 20 rounds fired at very high pressure. The other thing that is going to be trick is rigging the trigger to fire the AT2k.
There is another way I think to look at applying an at2k to a RF20 would be to attach the at2k to piston valve on the RF20 wich would still auto advance it and fire at high pressure, at leat I think it would.
All this is theory, I'm looking at my Powerclip, which I know is similar to the RF 20 in design. and what I have concluded is that the piston valve moves forward pushed by the pressure from the air bladder until it advances the clip up one position at wich point the valve releases the pressure to the barrel now in line to be fired.
So the mechanism moves the barrels then fires. Thus if you epoxy or plumbers glue an AT2K an RF20's piston valve it should rotate the barrels once and release a higher ammount air pressure in one instance.
I'd like to test this theory, but lack the guns. I can get an RF20 at TRU redily enough but I have a drought on the AT2k's.If I ever try it out I'll let you know about the preformance.

a) It makes more sense.
b) You wouldn't be able to fire the first dart if it advanced the clip/turret before firing the dart.
I don't quite understand all of your post, but I just thought I'd bring these points up.

My idea is not to make a rapid fire gun. Just a gun with better range that you wouldn't have to spend time reloading. Idealy it would fire once and advance the drum/clip after fireing the dart much further than a normal automatic. I suppose the other potential problems with the idea are that the RF20 barrels are really short and most of the higher air pressue would be wasted there, and that it may not send all the extra pressure to the dart, but rather advance to the next round and fire again, but with not added velocity and reduced ROF.
I am curious texasmustach, did you attach the at2K air chamber to the rubber air bladder of the rf20 or directly to the valve that moves advances the barrels and fires? What I'm think of is the latter idea.
