My first combustion cannon, which shoots airsoft bbs pretty fast. Chamber is 3/4" pvc, and about 10 inches long. Butane is the main fuel. Here are some pictures now.

Full rifle.

Trigger, and that part on the top of the tee is pulled out to spray the fuel in.

And thats about all. Thanks for looking!

Very cool dude!! I like how you incorporated it into the old gun stalk!! I know I'm just a noob, but 0n a scale of 1 to 10, I give it like a 7. Paint it up and the number goes up to a 8. Overall, good job and good design!! Just paint the pvc though, I would leave the stalk alone.

The pvc is fine really, I actually like the look of it on the wood.

I presume that's a genuine Mauser stock, if so it deserves a bit more respect than a ghetto combustion - still, good effort.

Yeah it is, same one from my sprinkler valve rifle. I have had other designs on it, but this on looks the best. I just need to get to work on a 1/2" QEV with a magazine and stuff so I can use it in airsoft with a bit more effect.
