K'NEX Thompson M1, by Miles "Tails" Prower
That is my new K'NEX gun. It is very simple to build so an Instructable won't take that long to make. (BTW: Sorry for the minigun, I'm busy right now) And uhh, it is powerful, good looking, and has a true trigger. With only 1 rubberband it can pierce a box (Sadly not clean trough). Well uhh, enjoy!
