See our Gun Dealers policy summary for a comprehensive discussion of this issue.
Federal law requires firearms dealers to obtain a license from the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), although resource limitations prevent the ATF from properly overseeing all its licensees.
Kansas does not require firearms dealers to obtain a state license, or significantly regulate firearms dealers in any way. See the Kansas Private Sales section for laws that apply to gun sales generally. See the Kansas Background Checks section for laws that require federally licensed dealers to conduct background checks on firearm purchasers.
