yeah thats what it looks like. You shoul use 3/4 cpvc for the barrel though because its the best fit.

nice job with the basic over under design. the only flaw i see is that it would take time to reload this sucker. an added breech would be really cool.

:D I like this gun. But i have a remark, are you filling that up to 60+ psi each paintball shot?.... because thats reallllly anoying. I have one aswell but i rarely use that barrel because paintballs cause no damage. And at the price making a canon like this one, arent you better off buying a talon.

in New Zealand i can only find 6mm PBs and .68 caliber PBs which is 17mm, i need a barrel for a PB rifle im builing but i cant find 6mm pipe and they only stock 15mm or 20mm pipe where a .68 caliber is 17mm,
Can anyone help me?will a 20mm barrel be fine for .68 caliber PBs?

actually, 3/4" SCH 120 PVC pipe is the best fit for paintballs, hands down; good luck finding it however

with lots of wadding but thats no fun. I really hate that other countrys cant get stuff to make their guns. Think of all the other people that would have them and all the new ideas they would contribute.

.68 cal works out be around 11/16ths of inch I believe , I cant find any of that super heavy schedule pipe anywhere near where I live. I want a piece so that I can make a horizontal loader for my tippy 98C. For a loading tube 3/4 inch will work fine but for a barrel it is a bit sloppy unless you can find some of that 120 schedule they mentioned.

I found a really nice PB barrel in Bunnings the other day,it is 3/4 black abs pipe in the sprinkler section and it comes in meter threaded section(threaded each end NPT thread) i got a hold of some PB's the first time i has ever seen or felt them and i had trouble finding a good fitting pvc barrel so i used this stuff its not pressure rated or anything but it works great and it only going to be exposed to shot periods of a depleating pressure source.
