An FFL is $200 and is mainly for dealers. If you own one or even 3 guns, you really don't need one. An FFL only allows you to buy and sell guns, parts, and accessories. Usually at cost instead of retail. Unless you plan on having a large collection, you are barking up the wrong tree. Plus, you have to be able to list a place of business, which can be your home, but it has to be approved by local law enforcement. Which means no go, for us navy folk living in housing.
