This is my latest project! It is a soda-stream Co2 tank and the valve is 1/2

With 2 bars i shoot a rifle-shell about 100 meters. It is some leaks in the fittings and i will fix that soon!

How is the elbow held in, is it threaded?
Look if you must.

Shame it's single shot, you really need to but a bb chamber on that thing :)

Heh, looks like fun!
With that chamer you could up the pressure quite a bit, and add a smaller secundary firing chamber.
Also, if you spring-load the ball valve you'll more than double the power you have now :)
