OK well I decided I wanted to see if I could make the smallest truegger, mag fed gun yet. This is what I ended up with. I decided to give it a Spanish name just for the heck of it and because I was tired of giving a gun an acronym for what it is. It loads about 5 green rods ( I think) I wouldn't really use it as a war weapon except as a pocket gun of desperation. It is pretty fun to play with and makes for a great knex gun to bring to school in your pocket.
P.S. I don't really know why I'm posting this seeing how it can be built from one picture for the most part =P
Step 1: Handle/ Magazine
It's a basic handle magazine for green rods. The idea of extending it with oranges is credited to oompa loompa. You could probably shorten the handle further but it would make it rather hard to wield and leave the amount of ammo you can store very minimal.
1-3. All very easy. Make the first two and attach like so.
That wasn't so bad huh? Moving on.
