The criteria for rifles that are subject to the multiple sales reports are (1) semiautomatic rifle; (2) capable of accepting a detachable magazine; and (3) caliber greater than .22 (including .223/5.56 caliber). Rifles with receivers that will accept a detachable magazine meet criterion (2). Such rifles include those weapons that have parts and/or accessories that allow the exchange of detachable (including clip or drum-type) magazines, such as the “bullet button.” Contact the Firearms Technology Branch at (304) 616-4300 for determinations as to whether particular rifles are subject to the reporting requirements.
