Do some research into MN law, you can legally purchase and posses a full auto in your state... I used to live there. You just need to go through the right steps to do it. It's like driving a car, you get a license to do that right? And a tractor-trailer, you have to get licensed for that too, correct? Driving either are against the law if you haven't taken the proper steps to become licensed.

And about this not making it full-auto, while there is not much difference in the number of rounds fired between pulling a trigger repeatedly in very quick succession on a semi-auto vs holding the trigger on a full-auto, the fact is that you're removing the need to release the trigger for the next round to be chambered and fired. How does that not make this full-auto?
