Critique: Changeable Barrel Coaxial 2" Piston Cannon

Please critique any problems you see, already had it told to me that I'm missing a ball valve before the quick connect.

Thanks!

Alright, so the idea from the changeable barrels comes from the fact that there is a 1.5" female adapter in the bottom of the standard 2.5 inch barrel, so anything 1.5" or smaller should fit in the 2.5 barrel just fine. Besides that, I only drew up the bottom half because the top is fairly straightforward, the 2.5" pipe flush with the 4" to 2.5" bushing. Also, it is fired with a 2" piston and... thats it I think. Thanks for any comments!

Umm why start a new thread when you already had it going on the other one? I like your design, it's a pretty compact way of doing it... You also have the pop effect going on because of the small difference in piston and seat diameter so that's good. I like it.

Yeah sorry I started a new thread, people were (critiqueing?) it in the other thread, but I wanted to make one with a title that said "hey come critique me!"
