Nice cannon, but I agree with most a larger chamber would greatly improve the velocity of the projectile.

why would you only want to shoot it once, Shoot a bunch of houses and piss your neighbors off!!!!

nice overall gun a little big for me b/c I am a little guy, but i'd still shoot it. Does it kick?

that gun has a simple yet effective design. just like drac says, it was designed to do a specific job and whatever it was it seemed to have worked.

once again, I must tell people that it does not matter what type of ammo you use, you can use anything that fits or you can force into the barrel.

very simple gun.You don't even have to glue them. Those things can leave some pretty big welts if you add a ball valve, and a schrader valve. Attach an air compressor to it and blast away Say hello to my little friend.

nice job putting this thing all together. overall a very clean looking gun and I look forward to seein future posts by you.

that has got to be a pain to lug around especially for a war.

that has got to bomb a golf ball a heck of a distance.

the bipod or whatever it is called looks pretty cool.

hey Zeigs can you make a quick tute on how to make a silencer for the "Newbies"

I want to build one of these. Can you please send me the plans. Thanx!!

Kick butt double chamber metal combustion.....enter it into the combustion cannon showcase!!

I might make one of these. I have a purell bottle around here somewhere..........

about how long is the gun?
