can i buy a gun at a gun show without background check
Under federal law, private-party sellers are not required to perform background checks on buyers; whether at a gun show or other venue. They also are not required to record the sale, or ask for identification. This requirement is in contrast to sales by gun stores and other Federal Firearms License (FFL) holders, who are required to record all sales and perform background checks on almost all buyers, regardless of whether the venue is their business location or a gun show within their state. Access to the National Instant Criminal Background Check System (NICS) is limited to FFL holders.
