This is my fully/ semi-automatic paintball rifle. I used 3" pvc for the chamber and 3/4" ABS for the barrel. Obviously it's an electric solenoid valve.
I can get 6 shots out of 80psi so I'll still need to built my other design to get better efficiencey after my chamber runs out. Other than that you can get 6 shots in a row.

First of all, I seriously doubt that you could fire a paintball through a metal door. Second, YOU PLAN TO FIRE THIS AT PEOPLE!!!! What is wrong with you! If it goes through metal, what would it do to something soft and fleshy!!!!
where does he say he wants to shoot it at people?...just because its a paint ball gun doesnt mean he will shoot it at people...atleast i hope not other wise this is a very nice gun i like it lol.

I think he implied it in his co2 regulator post.
But besides that bro theres a lot of tape on it why dont you replace tape with pipe clamps or whatever theyre called.

4.If you have enough grease & a big enough hammer, you can put anything... anywhere
3.If all else fails, hit it with a big hammer
2.Matter will be damaged in direct proportion to its value
1.If anything simply cannot go wrong, it will anyway
Hose clamps i think lol and i never saw where he said he would shoot people but please do not shoot anyone with this gun unless you can keep the painball at 300fps or lower thats what normal paintball guns shoot at lol.

I'm making a new cannon anyways so it'll look a little better. The only problem is that I need the tape the trigger which is not pvc to the gun.
On the new gun I'm putting on 4 reserve tanks and a main firing tank with a pressure of 70psi. The reserve tanks will hold 150psi.
So far it looks like a massive shotgun. It'll wind up looking like a rifle/shotgun mix. Kinda like the acid shotgun from the X360 game PREY.

This may sound like the standard bullshit post, but...
When you make your next cannon, don't use DWV PVC. It's only made for drain loads.
Look for either NSF-PW, (meaning it's rated for potable water, which is 99.9% of the time at pressure), or an ASTM pressure rating on you fittings and pipe.
Other than that, nice gun! Like everybody else said, don't shoot it at people! Save that for the cheap mexican slingshots.

cheap mexican slingshots...lol
I used regular schedual 40 pvc for most of the gun. Only the barrel is made of ABS piping and I know that that stuff isnt meant for pressure. The piping is rated up to 260psi so I should be fine. But what do I know.
