takes c02 cartridges, i screw, a 1 inch to 3/4 inch threaded reducer, and put on a 3/4 sch80 barrel, the barrel isnt on in the pic, because im using it on another project.

how does that work? is there a nail that puntcures the end of it?

CHEATER!!! thats one of those drain flusher things. I have one of those.

Wait a sec... do you really think any kind of plastic can hold the pressure inside a CO2 cartridge?

so what?
fiveseven, its like 40 psi of flow.

I calculated the barrel to chamber size at 100psi and i use a quick fill co2 changer for paintball right into my resovoir. It fills a 10" long 2.5" wide cahmber to ~100psi. It then boes to a modded sprinkler valve and then to my barrel. It does work tho, i can shoot potatoes about 200 yards sometimes more. these co2 do have alot of pressure and if your potato doesnt get shot and pressure builds the whole thing could go boom

Try a grammer lesson man... That post seriously made me feel like I was on drugs when I read it...

Your chamber has about 49 cubic inches of volume... So a 12 gram co2 should fill it to about 90 psi according to http://www.spudfiles.com/spud_wiki/inde ... _cartridge

paintball mortor? And how do you get the pressure out of the CO2?

just slam it down, and this little sherp thing piercxes the co2 cartridge,
and frogy, it has a vent theng that if you get over 70 psi it lets out all the air.

So is it one Co2 cylinder for one shot? That could be expensive.

yes.... thats why i dont use it very much.
