SPRINGFIELD, Mass. (WWLP) – Assault weapons have been banned in Massachusetts for nearly 20-years, but Attorney General Maura Healey said, that hasn’t stopped the sale of copy-cat assault weapons.

Healey said the gun industry has defied and exploited the state’s assault weapons ban by selling guns that are extremely similar to assault weapons. Healey’s office said last year, an estimated 10,000 assault weapons were sold in Massachusetts.

The Attorney General sent gun sellers and manufacturers an enforcement notice on Wednesday, prohibiting them from selling weapons that have key functional components that are interchangeable with assault weapons.

The state will use a similarity and interchangeability test, to determine whether a gun is too similar to an assault weapon. If is it, the sale of the weapon will be prohibited in Massachusetts.

Gun stores who already carry newly banned weapons will be forced to sell their stock to other stores in different states, where they’re legal.

The Attorney General’s office banned the following weapons:

  • Avtomat Kalashnikov (AK) (all models);
  • Action Arms Israeli Military Industries UZI and Galil;
  • Beretta Ar70 (SC-70);
  • Colt AR-15;
  • Fabrique National FN/FAL, FN/LAR and FNC;
  • SWD M-10, M-11, M-11/9 and M-12;
  • Steyr AUG;
  • INTRATEC TEC-9, TEC-DC9 and TEC-22; and
  • Revolving cylinder shotguns

Many gun owners and sellers have spoken out against the new regulations, arguing they were given little, to no notice.

The crackdown on assault weapons comes after several mass shootings have occurred in recent months. On Wednesday, Healey spoke about the importance of addressing the issues that have led to these mass shootings. “There is one issue that can be addressed right now, the proliferation of guns, particularly assault weapons,” she said.
