Following is a summary of the 2013 legislation:

- 120 specifically-named firearms;

- Certain other semiautomatic rifles, handguns, shotguns that can accept a detachable magazine and have one or more military characteristics; and

- Semiautomatic rifles and handguns with a fixed magazine that can accept more than 10 rounds.

- Strengthens the 1994 Assault Weapons Ban and various state bans by:

-- Moving from a 2-characteristic test to a 1-characteristic test;

-- Eliminating the easy-to-remove bayonet mounts and flash suppressors from the characteristics test; and

-- Banning firearms with “thumbhole stocks” and “bullet buttons” to address attempts to “work around” prior bans.

- Bans large-capacity ammunition feeding devices capable of accepting more than 10 rounds.

- Protects legitimate hunters and the rights of existing gun owners by:

-- Grandfathering weapons legally possessed on the date of enactment;

-- Exempting over 900 specifically-named weapons used for hunting or sporting purposes; and

-- Exempting antique, manually-operated, and permanently disabled weapons.

- Requires that grandfathered weapons be registered under the National Firearms Act, to include:

-- Background check of owner and any transferee;

-- Type and serial number of the firearm;

-- Positive identification, including photograph and fingerprint;

-- Certification from local law enforcement of identity and that possession would not violate State or local law; and

-- Dedicated funding for ATF to implement registration.
