The Brady Handgun Violence Prevention Act (Brady Act) provides crucial information about firearms buyers to Federal firearms licensees (FFLs), but does not help nonlicensees to identify prohibited purchasers. Under the Brady Act, FFLs contact the Federal Bureau of Investigation’s National Instant Criminal Background Check System (NICS) to ensure that a purchaser is not a felon or otherwise prohibited from possessing firearms. Until the Brady Act was passed, the only way an FFL could determine whether a purchaser was a felon or other person prohibited from possessing firearms was on the basis of the customer's self-certification.
