Its as far as i could get it. Same with the tee and elbows. I found the book in the creek and thought it would be a good target. I cant believe it went through.

If the bushing is too long to fit into the socket, why not cut a small length off the end so it fits flush?

All of the parts are NSF-pw (or so it appears). if that is so, the bushing should not need to be cut down; it should fit flushly no matter what. I have a recommendation for your next cannon: spend a couple bucks and buy a rubber mallet. They are honestly GREAT; they make solvent welding so much easier. You just pound in the fitting with the rubber mallet (while attempting to make a quarter turn), and then you just hold for 30 seconds

people have gone to 110psi with it,so you could put it around a brick wall and you stand on the otherside of the brick wall and pump it to 100psi

I recommend you trash it and buy NSF-pw. The launcher just will not be very fun if you always have to worry about the thing exploding; you will be glad you bought the fittings.
