I have two ideas for my air tank design for my portable bbmg. My theory is that since I am firing in very quick bursts, a small tank after the regulator would be emptied faster than the regulator can supply air directly to a blowgun. What do you think? Here's a diagram:

put the fill valve before the regulator, those things don't work well two ways. Your reg should be able to keep up with your BBMG, so you don't need the expansion chamber

Ok, thanks for the suggestions. I think it would look cooler without the other chamber anyway.
