"...The obvious, Gatling...." Doesn't use a rotary magazine. Even those big 'peep sight' looking mags aren't rotaries.
"...the system is designed to work best for 410 and 12 ga..." What's the point of a 2 shot rotary shotgun mag? Other than as a 'Can I do it?' excersize.
He sez it's a "fantastic rotary feeding weapon". Not that it was a rotary mag.
The description given,could cover an electric spaghetti fork with a sharpened up edge, and really does not give away much in the way of info, so I'd say his secret is safe enough from the likes of us.
Though I really gotta ponder how any system that would work on the larger and skinny ends of the shotshell size range, should be exclusive to working on the others.
Research, money, marketing, money, lawyers, money, more research, money....etc.
I met a couple guys that have invented some things that they made money. Some of them were obvious, once you saw them, and cheap to make, others less so.
If you can get a product to market, and still have food in the fridge, you will be doing better than the average inventor.
I have been asked to help build parts for inventions too. Usually by guys wanting me to sign 10 pounds of paper promising the earth and stars that I won't ever speak of the "product", before they will supposedly allow me to be privvy to the information. They want, in general to pay in "shares".
All them were nuttier than Christmas cake, and one of them was inventing stuff that was already not selling well in the surplus section in Princess Auto.
Get the patent, get an agent, and a lawyer. Getting a patent is easy enough. Getting any money for it, is harder, and getting any money from a corporation, esp. one offshore, that is knocking off your patent, even moreso.
