I imagine you are referring to the info in U.C., and I would suggest you call Kent Lamont -- as I believe he was the model for the class III dealer in the book.
Kent has relocated from Indiana to Idaho. Number is 208 756 6819. Another good source would be Dan Shea, who authored the Machine Gun Dealers Bible, 207 683 2959, E mail,
[email protected]. The info on Dan is from SAR.
Last, I would not give information/advise on modifications to make guns full auto, just because I do not have the kind of money that can be chewed up in a court case. The government does not have to win, all they need to do is bankrupt the individual. Ask Bill Fleming, they did both to him. GLV
