I just guessed at the price range. It involves the casting of the frame, or CNC milling from a block of metal. Then the reverse or left-hand slide would jack the price up more.
I agree with 270, because they can, which is a much more elegant way of saying what I did. They are showing off his (their?) skills. And those are formidable.
Shooting it would be interesting. If they were demonstrating it I would pay $5 to run 2 full mags through it.
I remember Armalite being at Rio Salado range as a vendor at one of the major matches. After the match you could pay a nominal fee to shoot one of the display models. Most went for shooting the .50 BMG rifle. I wanted to try the AR10 but it was late and I was tired.
It would be fun to have all of the 'fun guns' at the range at the same time so you could try them all out at one time. Let me see: a .50BMG, a .408 Chey-Tac, the double .45ACP, ooh a full magazine of .375 H&H through the Fuchs and Szecsei double rifle, a 200 rd. belt through the M249 and an M60 and oh what else?
OOPS sorry, did not mean to hijack the thread.
