Super-small chamber fan inspires me to....

... design a combustion sniper gun. Probably silenced. I'm thinking 3/4" sch. 80 barrel to take paint balls and patched marbles. Maybe bolt action? I've started sketching some designs. Definitely metered propane! I found some small propane tanks but I want to get one first and play around with it and make sure I can get the fittings to make it work. Probably a 2" chamber, shooting for a .7:1 C:B and then a large silencer... I want this one to sound no louder than a mouse fart.

I'll post updates as this comes along.

Sounds fun already. The fan should work great.

Maybe you could try an external syringe injected propane system of some sort instead of trying to mount a propane tank onto that size gun.

Keep us posted.
