I went to his web sight and there doesn't seem to be anything for sale. It's hard to imagine that he has 1000 guns manufactured and hasn't made a clear path to purchase. Or perhaps they are just not available here in the USA.

I'd think a US patent would just be to prevent a direct copy by a US manufacturer. Doesn't seem to stop the Chinese and other countries but I guess it's some protection. Often times these inventions are bought up rather quickly by the big boys to either sell under their names or to kill the thing early.

Neat looking gun. What type of scope would you use on the thing. Pistol, scout rifle. or conventional rifle scope.
