question:
Federal law requires background checks for commercial gun sales, but an exemption exists for private-party sales whereby ``Any person may sell a firearm to an unlicensed resident of the State where he resides as long as he does not know or have reasonable cause to believe the person is prohibited from receiving or possessing firearms under Federal law.'' Under federal law, private-party sellers are not required to perform background checks on buyers, record the sale, or ask for identification, whether at a gun show or other venue. This is in contrast to sales by gun stores and other Federal Firearms License (FFL) holders, who are required to perform background checks and record all sales on almost all buyers, regardless of whether the venue is their business location or a gun show. Some states have passed laws to require background checks for private sales with limited exceptions. Access to the National Instant Criminal Background Check System (NICS) is limited to FFL holders.
answer:
is a background check required to buy a gun at a gun show?
