I had an ATF Agent contact me last week about an AR15 (that I had sold almost 2 years ago) being among some weapons found on a truck headed for Mexico. There was no real discussion, only that he was advising me of the fact and made reference to 'Fast and Furious'. . Along with that he advised me that due to the number of transactions that I had had over the last few years that I should submit the necessary paperwork to obtain an FFL License. I have also learned that a few other folks in the area have also been contacted and advised to do the same thing. I have been a collector of firearms for over 35 years and have bought, sold and traded weapons over this time but it is not a 'Business' for me. My primary goal has to improve my collection and the majority of my my transactions have always been through an FFL. I am also wondering if there has been a significant increase in ATF 'Contacts' with other 'Hobbiests' recently. Any advise would be greatly appreciated.
