I've been doing some research on the ATF website and browsing this site some. Do I need an FFL to purchase a Class III weapon? I ask because I do NOT intend to sell weapons, just purchase them for my own enjoyment. And I found a sweet AOW shotty with a 6" barrel that I just have to have. So, how do I go about getting the ok to purchase it? Also, can I carry it with my concealed weapons permit?
