It's a good battle Jerry, best of luck with it.

Fortunately, you did mention possible problems. Getting just one expensive gun tied up in the system could cripple a small business and many don't have the time or money to invest in legal research or protection. Maybe, there are credible organizations who would put out legally reviewed guidelines, that are regularly updated for changes, to interested sellers. I suspect referring the average person to any law on the books would overwhelm them.
