The ATF inspects the premises of all licensed gunsmiths with unannounced visits at periodic intervals. The ATF is granted the power by the U.S. government to initiate the prosecution in U.S. federal court of gunsmiths that wilfully omit or violate these provisions. Punishment can range from losing their FFL (and therefore the privilege to engage in any firearms-related business), to fines and in severe cases, such as conspiring to supply the criminal element with black market weaponry, imprisonment in a federal prison.
