BB pistol plans I drew, would they work?

This area is for the discussion of BB or airsoft sub machine guns, and or other small arms such as pellets.

Good point jack, but now I have a better idea.
Go to a $2 shop and buy somthing like this:

I used to be able to buy cheap versions of these for about $2. If you cut the end off the pump it would give you a good piston and a tube that it fits perfectly in. Best of all it should have fairly low drag.
