Has anyone attempted this before? I took my RF20's bladder, and cut about an inch off of it, but so it was still longer than the PC's bladder. I then put it in the PC. I was wondering what a bigger bladder does for the gun. It allows more air to be stored, and if I put a lot of bands on the bladder do you think that it will allow all 10 shots to be shot at a much further range? If so, what is the recommended bands to put over the bladder.

You should also take into consideration that it would take almost as many pumps as an RF20 would to prime it, which defeats the tradeoff of 20 shots for more pumps to 10 shots for less pumps. I would cut the bladder to less than the length of the PC tank, to do what Yakman did.
Just suggestions.

Doesn't that make the PC unable to fire all 10 shots because of the decreased amount of air pressure? And doesn't it also eventually make the bladder explode?

Cutting bladders...yikes. Yakman's mod is definitely worth a look; I was thinking the same thing as TS. The only thing is that I've heard of more problems when cutting a bladder than I've heard of praise. Yes, it may lead to the rupturing of your tank. If you have several to spare, I would say go for it. I just know I couldn't do the same to mine, as I'm too attached right now. To be Frank, I would stick with banding, or bike tubing. It's up to you. Best of luck!

Dosent Pc take 20 and Rf20 take 20 pumps?

[deth moad ue]

My RF takes about 25 - 28 pumps to fill all the way (any pumps after lose air via the overpressure valve).

No. The PC takes 15ish pumps to fully prime for 10 shots. The RF20 takes upwards of 30 to prime with 20 shots.

If you want to try and not have to pump the gu nas much, then just make a bigger airtank out of 1 1/2 inch to 2 inch PVC. Connect it to the gun and have it in a backpack/taped on the side with one of the 6 dollar K-mart hand pumps in it to pump it up. I have heard of only haveing to pump it every now-and-then with fring able to fire aprox. 50 to 60 shots. Maybe you could aquire many PC clip and somehow put them all together to make a huge 40 round clip. HEHE.

You're confusing air capacity with air pressure. If you have a smaller bladder it takes more pumps to fill it to the overpressure release thingie, so you not only have higher air pressure inside (higher mass, lower volume if you know any fluid physics) and you have more air overall. But of course I have heard of it eventually rupturing the tank, so what I would do is keep a few well cut pieces of bike tube around whenever you war for a quick replacement.
