Assault Weapons Ban and Law Enforcement Protection Act of 2003

Assault Weapons Ban and Law Enforcement Protection Act of 2003 - Amends Federal firearms provisions to revise the definition of "semiautomatic assault weapon" (SAW) to include conversion kits (for converting a firearm to a SAW) and any semiautomatic rifle or pistol that has an ability to accept a detachable magazine and that has any one of the following characteristics, respectively: (1) a folding or telescoping stock, a threaded barrel, a pistol grip, a forward grip, or a barrel shroud; or (2) a second pistol grip, a threaded barrel, a barrel shroud, or the capacity to accept a detachable magazine at a location outside of the pistol grip.

Amends: (1) the Brady Handgun Violence Prevention Act to reauthorize the assault weapons ban and add new restrictions; and (2) the Public Safety and Recreational Firearms Use Protection Act to repeal the sunset provision regarding restrictions on large capacity ammunition feeding devices (LCAFDs) and on specified SAWs.

Modifies the exemptions from the Brady Act's prohibition against manufacturing, transferring, or possessing a semiautomatic assault weapon to exclude: (1) specified firearms, or replicas or duplicates, as manufactured on October 1, 1993; (2) any semiautomatic rifle that cannot accept a detachable magazine that holds more than five rounds; and (3) any semiautomatic shotgun that cannot hold more than five rounds in a fixed or detachable magazine.

Prohibits the transfer of a SAW except through a licensed dealer or a State or local law enforcement agency, subject to specified requirements. Directs the Attorney General to: (1) establish and maintain a record of the make, model, and date of manufacture of any SAW which the Attorney General is made aware has been used in relation to a crime, and of the nature and circumstances of the crime involved; and (2) annually submit the record to Congress and make the record available to the public.

Prohibits: (1) the transfer of any assault weapon with an LCAFD; and (2) a licensed manufacturer, importer, or dealer who transfers an LCAFD that was manufactured on or before September 13, 1994, from failing to certify to the Attorney General, within 60 days of the transfer date, that the device was manufactured on or before that date. Sets penalties for violations.

Prohibits: (1) the transfer of a SAW or an LCAFD to a juvenile; and (2) the importation of an LCAFD.
