The rifle transactions that must be reported are dispositions of semiautomatic rifles capable of accepting a detachable magazine and with a caliber greater than .22 (including .223/5.56 caliber) to an unlicensed person. However, the reporting requirement does not apply to receivers for such rifles.

You may contact the Firearms and Ammunition Technology Division at fire_tech@atf.gov or (304) 616-4300 if you are unable to determine if the rifles are subject to the reporting requirements.
