Combustion based bb/airsoft gun ?

[yuandrew]

I haven't been here for a while (been busy with other hobbies and schoolwork) but this was something I thought of a long time ago when I made a couple mini-launchers that fired using film containers. I started with design that was simply a combustion gun scaled down then later drew up a "pistol" version.

Inspired by someone's animation of a Tippman C3 propane fueled paintball marker, I ended up creating this animation. I still haven't figured out the loading and fueling sequence but you can figure out what happens when the trigger is pulled.

Cool idea. Very cool idea.

The reloading can be done using a blow-forward breech that shouldn't be too hard to construct.

However, some potential sticking points:

1) venting the chamber in between shots, you might need a chamber fan permanently blowing towards the barrel.

2) more critically, metering the exact amount of butane from the lighter

great idea but work out the kinks like jackssmirkingrevenge said

I really like this idea, I think its got great potential. I have no ideas on the metering system for the butane, however, the bbq ignitor could be replaced with a small stun gun ignition, although then you do need a battery and place for circuit, but you would eliminate the need for a trigger. Plus a button is a lot easier to push than a bbq ignitor, PM me or aim me or something if you want to know more about my stungun idea.

Good Luck
