Frequently asked questions

What types of firearms does GunsAmerica offer online?

Are there any restrictions to buying legal firearms from GunsAmerica?

When buying legal firearms from GunsAmerica, you are subject to state, federal, and local laws. Certain firearm types, such as Class 3/NFA firearms, may require additional documentation and clearance. Before purchasing, comply with all local, state, and federal requirements.

What are some of the best firearm companies available at GunsAmerica?

At GunsAmerica, we take pride in offering a wide range of top-notch firearms from the best companies, including Glock, Sig Sauer, Smith & Wesson, Beretta, Colt, Heckler & Koch (H&K), Ruger, Springfield Armory, Browning, FN (Fabrique Nationale), CZ (CZ-USA), Daniel Defense, Kimber, Walther, Tikka, Weatherby, Barrett Firearms, Wilson Combat, Christensen Arms, Benelli, and many more.

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.
