It is a pneumatic gun that runs off of a mix of air and butane, and fires multiple times from one charge,
It uses a fire extinguisher as a primary tank, then looks like it feeds to a smaller one that it fires from.
You don't need to speak french to appreciate this...

Even if you can't speak french, the pictures might help...

Any ideas as to how this would work would be greatly appreciated, because that looks like one fun gun to shoot!
EDIT: I looked up the maker, and found this video of him charging and firing it some,

And since it is just a tiny squirt of butane, it doesn't look like it would really contribite that much, and also looks much like it would be a good feed for a semi auto combustion, so this is just leading me in all different directions
