link?
Link? I don't sell the bloody things over a website! The patent is currently licensed to a firm in Colorado that sells equipment only to military and LEO's. They only make a few thousand rounds per year of my little toy thus I don't make a lot of money on it.
My point, again, is that the only hassles I had when developing the thing was from the local county mounties. The Feds didn't bother me at all.
I'm no big fan of the Feds on guns and gun control, just pointing out that development is not a prohibited activity. If you want to develop a military application full-auto you can get a permit via any number of agencies to circumvent the ATF. DARPA is one of them.
