Attorney General Maura Healey has "not yet" cited anyone as part of a stepped up enforcement of the state's assault weapons ban, targeting "copycat" firearms, she said on Monday

Gun rights activists and Republican lawmakers rallied on Beacon Hill Saturday, resisting the attorney general's plans for a crackdown on copycat weapons.

Speaking to reporters at the Philadelphia hotel where the Massachusetts delegates to the Democratic National Convention are staying, Healey said gun sellers had received the message, and a spike in sales that followed last week's announcement has since subsided.

"The action we took was about closing the loophole, making clear that people understood the law, and making clear that people understood that we were going to enforce the law," Healey said. "The good news is that while sales were up the day of the announcement, sales continued to drop precipitously over the next few days. We continue to monitor sales, but I think what's clear is that gun dealers, gun manufacturers, have gotten the message that this subset of weapons cannot be available under existing law. I’m not creating new law. This is under existing law."

Gun Owners Action League of Massachusetts Executive Director Jim Wallace said lawmakers have had a chance to add guns to the assault weapons ban.

"These laws were passed in 1998, they were redone in 2004, then they were reviewed in 2014, so the Legislature is already fine with what is going on," Wallace said Wednesday. "What other reason would a person unilaterally decide, I'm going to change the rules overnight?"

Asked about enforcement actions and whether anyone had been cited since the crackdown, Healey said, "Not yet."
