SpudFiles

I was looking at the design used in paintballs. So I put together a blow forward design. I wondered if this could work as a full auto? If it would work maybe you could attempt to modify it to accept shells so you could use any ammo. Have them on a belt. I wanted to put a trigger system on it but couldnt figure out how to.

A trigger would just be a High Flow pushbutton valve...

Look at the valve on the sprinkler modding tutorial, that's not a blowgun, it's a high flow air valve...

Nice design, it wold work, just not that way, the bolt woul need a seat by the ball port to keep it straight and you would have to make the thing that runs inside of the the bolt longer and cut holes in it and down the center of it, so intead of the bolt coming off of the guide to let the air out it just has to go out so far and it'll open...

It's been done.

Very simliar designs, eh?

EDIT: Not implying that you took his work, just commenting that they were similar in design.

His didn't work but I am sure a bit of work will get it going.

Maybe it would work on a smaller calliber like bbs?

With parts that small it will be very hard to make.

spudshots S.A.F.E works like that, but its semi auto.

yeah does any one here no how a blowback mechanism works? I live in australia and am desperate for a semi auto kinda pistol. Even though we cant get bbs here we can use dried peas with wadding.

There's a few other ones on there too.
