Looks pretty good, though I wouldn't take it above 60 psi. You have DWV elbows and a T, and they aren't meant for pressure applications.

I have taken it to 90 no prob. I am going to build another gun, as this was my first. It worked surprisingly well. I am kind of a pessimist, so I assumed that it was not going to work. I thought it was a fun first gun. Oh, BTW, sorry about posting this in the wrong place, I am a n00b on these forums.

Nice Job.
I just have one suggestion. The barrel could be twice that length and it would go faster. A C:B ratio of .8:1 seems to be the best.

The good thing about having interchangeable barrels is that you can put golf ball barrels on there, tennis ball barrels, anything that suits your fancy.

Well, today the plastic threads holding the metal pipe in broke. I am going to completely rebuild the elbow section. The elbows were DWV, and I don't want to blow up. So this time I am going to be carefull on what I buy. Also, I am going to put a modded sprinkler valve on there, so prepare for a Version 2.
