Hi guys, this shotgun can be looked as the cheapest generic combustion spudgun, or a pvc shot gun. It's unbelievable how easy it's made. My designs so far have been much more complex, this is very old design for me, but it works fine. It came to my mind after a lot of DOOM3 action. I wanted single shot short weapon with a lot of destructive power. I hope you like it.

Made my own version. Good tutorial and great performance! The small chamber is great for using syringe metering with butane. Worked first try, but I'll have to wait till tomorrow to actually get some test shots.
Mine is made with water bottles, which have thinner plastic, so hopefully it won't rupture. But I can cycle out the chambers since I have sooo many water bottles.

(White electrical tape + white PVC = pretty clean build)

ALSO I made a spacer using a small piece of PVC pipe to put between the piezo igniter and the elbow (barrel side). This gives a little more room for your trigger finger and keeps the back of the igniter flat against the pipe rather than jammed against the curved inside of the joint.

EDIT: Went ahead and finished the video haha. It has pretty neat still shots.
