Hopefully this one won't fail, good job.
I only have one minor complaint (maybe I'm just nitpicking): all of your combustion launchers look the same. :?

Nice cannon, I hope this one survives. :( It looks awesome, and the extra precaution while building it makes it more goodly.

I really like the way this looks, but one thing just stands out to me.

did you use the 1:1.5 ratio? your barrel seems awful large for 1.5" or(i'm assuming thats what it is) to both compensate for chamber size as well as the space in the u bend.

you did your math, but I would have just used a larger barrel size. with the u bend design you cant really have to small of a chamber or else your propane tank sticks out all funky like.

nice gun btw :lol:

looks like a pretty sweet gun... love the cam-locks... only wish I woulda thought to put em on my gun when I was making it... cuz maybe it's just me, but my barrel can be a real bitch to unscrew sometimes...

anyways, awesome gun man...
