In Oklahoma, who is responsible for conducting the background checks for firearm purchases?

The Federal Bureau of Investigation (FBI) is responsible for conducting background checks for firearm purchases in Oklahoma. This is because the FBI has a national database known as the National Instant Criminal Background Check System (NICS) that is used to perform these checks. The Oklahoma State Bureau of Investigation (OSBI) and Department of Public Safety do not have a national database, and the local police department may not have access to all necessary information from other states. Therefore, the FBI is the most appropriate agency to conduct these background checks to ensure comprehensive and accurate information is obtained.
