@kablooie: Steel is actually relatively cheap (in the U.S.) I think the chamber cost around 15 dollars, including the fittings. The whole gun cost around 50 dollars.

Would you really take it past double its pressure rating?

Why, it's a dog humping a pole. Also, the rating is probably for the piston in the qev, which would be the first thing in it to break, but I think it could handle more than 150 psi, just like the steel pipe (which is also rated to 150 psi.

Is there some cunny in that Metalingus?
Rifling looks a little fast/aggressive, to much twist .

There might be a little more than necessary, but the picture makes it look a lot worse than it really is.
What do you mean by cunny?

I agree with sjog, what’s the rate of twist, approximately; how many times did the dowel make a full revolution ?

I was thinking more about the puppy but whatever. You should give us more detail on the rifling

Alright, the rifling is approximately 3/4ths of a revolution over a 5 foot barrel, but the picture makes it look a lot more twisted than it really is. The picture was taken with a cell phone, so it was just bad quality.

Well ifin I did my math right that’s about 1 in 80, which’ll stabilize a projectile approximately .75”dia by 1.05” long.

It’s quite a little to steep for paintballs, requiring a rate of twist of 1 in 102.

As for the picture, no matter how high of grade camera you use it’ll still come out like that because cameras take 2d pictures. But from what I can tell the rifling looks pretty nice.

Thanks, and like I said, the primary ammo is co2 cylinders.
