What do you need to sell a gun?
This varies from state to state, with different rules applying to handguns and long guns. Some states are really draconian; others quite liberal. From the perspective of the federal government (and thus applying to all states), a handgun can only be transferred through an Federal Firearms Licensee (i.e., licensed gun dealer). Rifles with barrels of 15″ or more and shotguns with barrels over 18″ can be sold privately. Shorter barreled long arms and fully automatic weapons are subject to totally different rules and can only be transferred by a Class III FFL dealer, require a payment of $200, and a very extensive background check.
