Do not build this item.
I should call it: Ticket to Guantanamo. Imagine having this with you at the airport. Better yet, don't.
This item doesn't/no longer/didn't ever exist (This could be a really nice 3D render, I have the skills...).
The cable going into the ejection port plugs into the stock harness. It's the stock harness from what else, an M14 clone.
Somehow, a RC servo got stuck to the magazine.
A REAL briefcase gun has a piddly MP5K in it. A Beta Spetz would be the logical KGB construct. Makes more definite HOLES in things that need holes in them.
I fully plan to paint one end of this briefcase Bright Orange. That would look good, huh?
Enjoy the pics, but don't act on 'em.
