Using FN303 Magazines...

Well, get us some CAD of the FN Mag and lets see what happens!
Looks awesome. Dump chamber like a the D.P. markers? That'd be the smallest size I would think. Otherwise you could put the valve system into the grip possibly.
Air chamber in grip was my first thought- Mini style. The bolt action and well, a Barrel? My next thoughts.
Air source? 12 gram? Standard tank?
There is now way I would want to shoot something like that in real life. Would kick so much.
makes me think of this:

That would be better. Would love semi-auto or even select fire but that would take up a lot more room.
I would think 12 g would be best, however you'd probably need a reg unless you used a sheridan type valve or similar but that would change the size for sure. Some sort of regulated input would be necessary depending on the valve system.
I don't like having the tiny top valve thing so I haven't really developed this, but here is my micro valve. Not sure that it work reliably IRL.
The trigger (moves forwards, so requires a lever) pushes the bolt forward, which opens up the dump chamber and blow-forwards the bolt (it's missing the bevel on the back). The top valve is closed as the bolt moves forward.

You can also connect the trigger directly to an on-off valve to skip the miniature valve thing, though that can result in short stroking to a completely open valve.
The funny thing is - in this forum someone says "let's make this" and within 5 responses you already have 2-3 design ideas, a conceptual drawing, and a plan in the works. I think with the thinktank this forum is, if we had the machinery at hand and the time you guys could go from concept to prototype in 2 weeks time :)
Wow. I want one already.
