Can I sell my firearm to GunsAmerica?

If you are looking for the best place to sell firearms, GunsAmerica is your top choice. GunsAmerica is a marketplace where collectors, dealers, and private individuals can list and sell firearms. All you have to do is create an account and list your firearm. After the sale, the buyer is responsible for sending the firearm to their preferred FFL dealer so that the transfer can be legally completed safely and lawfully. GunsAmerica does not buy guns or sell guns directly, as we are a marketplace.

How does GunsAmerica handle firearm shipping and transfers?

All firearms bought on GunsAmerica must be sent to an authorized FFL dealer, and each seller on GunsAmerica will provide shipping information to the buyer to ensure a smooth, successful transaction. However, non-firearm items such as holsters, magazines, optics, and ammo in most cases (some state and local laws may prohibit), can be sent straight to your door. Before purchasing a firearm, communicate with an FFL in your area to advise you on shipping and transferring your firearm.
