firstly i would like to say this gun was PYRO NINJA'S idea, i made this one with him so dont post anything saying i copied him. To make mine different i added a stock to it, not much but at least its something :)

barrel: 60cm of 1/2 poly pipe
valve: 1/2 ballvalve
pressure chamber: 1 ft of 3/4 steel pipe
for ammo i use AA batteries, they fit in the barrel perfectly.

You know, every time I see a "first pneumatic" that looks better then my pneumatic it makes me want to volunteer at a soup kitchen...

I've heard batteries don't fly straight, but I've never tested that (parents think I'll melt myself).
Nice cannon, like I said, looks nicer than mine (maybe I'll post it tonight, 4 months after building it). Now you need to put a marble barrel on it and use it as a sniper.

80-100 psi(dont think so) those pumps hardly reach 30or 40psi( mine dindt) after i got another pump with a pressure tank in the side i could pump to 80psi.

I disagree with you PneuJose. I have a pump similar to that, and (with enough motivation and time) I can ge it up to 120. Usually, it isn't the pump, its how long you pump it for.

Very nifty cannon, much better than mine. Though mine was a walking timebomb when I learned about some mistakes I made. Anyway, good job.
