I never had any evidence of the buyers not being legally able to own them. I simply checked to make sure they were a resident of the state via their driver's license.

Having a higher willingness to pay could be a whole bunch of things; I just found there was a curious number of buyers that would pay over the going rate, which in a free market may have meant there was a reason for it.

I also take ideological issue with the felons cannot own firearms rules. Imo, if you've served your time, your debt to society was served, and your rights should be restored.

I was never under the impression that these weapons would be used for violent crime.
