This is my K'nex MP40 that I just finished making. I was looking for a gun that no one had made before and this was the first one I found, so I decided to go right ahead and make it.

The only copied part is the trigger from TheDunkis's AK47 and i modified a little bit his handle.

This is my first instructable so lots of constructive criticism!
