Hmmmmm. Reminds me of the ARES Folding Sub-Machine Gun of the 80's.
Very interesting, but I really doubt there is much of a demand for such a product. If I recall correctly the ARES worked well enough, but there wasn't much demand for a folding SMG, not when so many current SMGs can easily fit into a breifcase or laptop bag.
I would still like one though. ;D
