Full auto pengun with pre-charged cart's

Unread postAuthor: inonickname » Sun Apr 19, 2009 4:55 am

*I reserve the rights to use this design as a competition model- if you wish to use this exact design or a close replica of it please pm me*

This is my (basic) design for an inline pneumatic pengun that is full auto capable (well, you'll get a few round burst), incorporates a blow forward breech and.. has preloaded cartridges that are near failproof.

Yet there's one issue... It's impossible to recock without losing air tightness. Perhaps a strong rare-earth magnet would do the trick but that tends to limit me to ferrous metals for the bolt. Oh well..it's an issue to try and overcome.

So it's a hammer valve that uses a cartridge with a schrader as filling/piloting valve? You need to be a bit more clear with the mechanism.

I was contemplating minaturising the preloaded cartridge concept for pengun calibre now that I have 800 psi on tap.

Tiny preloaded coaxial carts shouldn't be hard to manufacture.

It's not a co-ax..however that would be good for size. It's a hammer valve coupled with a blow forward bolt. The carts are only loaded with air, the ammo is from a magazine. The schrader core should have the spring removed for moar.

The green bit is the schrader core, I just didn't bother to draw the rest.

Btw, got a new shocky. Guage goes to 300 but I can get it to 400 easy.
