I've had this idea for a while, but I was visitting lkmachines, and I found a gun that had an idea similar to mine.

An RBG, with a detachable mag. The magazine holds rubberbands, not actual pieces.

So think of having a handle, with a detachable top part of the gun.
Again, I have a picture of what I mean, but it doesn't want to be in the comment.
 A truly sub-machine gun out of knex.  It would work by having a large magazine, but instead of holding individual shots, it would hold barrels with a block trigger.
 and if you pull the trigger you release the magazine releases until you let go of the trigger, then the mag is blocked and it wont fire. a downside is that you have barrels littering the area.

Pretty much all chain fed guns are like that, they just have a chain, not a mag.
I think DJ Radio made one that was semi auto.

I don't know if this has been tried before, but I thought it was interesting. I was inspired by an article about dual-stroke revolvers.

Extreme Builder was the first. Search for his truely semi auto gun.
Ah, thanks.
 Would any of you like me to post instructions for a knex transmission? Three speed+ reverse? I am developing a fully- automatic transmission for a rock crawler.
