The Bay States’ already strict gun laws were made all the more stringent on Thursday when the governor signed sweeping new gun regulations into law, creating live fire requirements for new license holders, and banning most “assault-style firearms.”

A statewide registration system was also added among a broad range of other provisions.

Jim Wallace, the Executive Director of the Gun Owners Action League, told the Herald that GOAL will challenge the law in court.

According to Gov. Maura Healey, An Act Modernizing Firearms Laws is meant to respond to the U.S. Supreme Court’s decision in New York State Rifle & Pistol Association, Inc. v. Bruen, which overturned state laws making it more difficult to obtain a firearms license, and as a reaction to the growing prevalence of so-called ghost guns.

“Massachusetts is proud of our strong gun laws, but there is always more work to be done to keep our communities safe from violence. This legislation updates our firearms laws in response to the Supreme Court’s misguided Bruen decision. It cracks down on ghost guns and 3-D printed weapons, which I have long advocated for, enhances our ability to prevent guns from falling into dangerous hands, and invests in our communities to address the root causes of violence. This law will save lives,” Healey said in a statement.

The law, which passed with the support of the Massachusetts Chiefs of Police Association, was met with widespread praise from gun safety groups.

“For years, we’ve been on the frontlines, advocating for our lawmakers to enact this gun safety bill into law, and we couldn’t be more excited to finally see our hard work pay off as the Governor signs this critical legislation into law,” Moms Demand Action Massachusetts volunteer Maxine Slattery said.

“Today, Massachusetts can hold its head high: our reputation for strong life-saving gun laws just got even stronger,” Grassroots for Gun Violence Prevention founder Jennifer Robison said.

“Gun violence is an evolving challenge that requires a comprehensive set of solutions. Whether it’s stopping the flow of untraceable ghost guns into communities or banning Glock switches and other similar devices, this bill tackles those head on,” Former Congresswoman Gabby Giffords said.

Wallace has described the law as a “tantrum” by lawmakers in response to the Supreme Court’s decision in Bruen, which ended the state’s long-standing practice of leaving a person’s eligibility for a license to carry a firearm to the discretion of their local police chief and whatever hurdles they might imagine necessary.

According to GOAL’s review of the law, it expands the state’s “two feature test” for determining what qualifies as an “assault-style firearm” to effectively ban “every firearm that is semi-automatic centerfire utilizing a detachable magazine” and would prohibit the purchase, sale, transfer, or import of AR-15s or other similar-style weapons after August 1.

It would require gun owners to register all of their firearms with the state, including partially assembled weapons except firearms made before Oct. 22, 1968, to report ammunition purchases at the point of sale, and ban automatic weapon conversion tools like bump stocks and auto sears.

The new law will raise the age to buy a shotgun or rifle in the Bay State to 21, prohibit the carrying of firearms in polling places, government buildings, or schools, and broaden the list of people who can file for an “Extreme Risk Protection Order” to include school administrators and healthcare providers.

The law bans the possession of “unserialized” weapons, otherwise known as ghost guns, which can be made using a 3-D printer or assembled from a kit.

Under the new law, new firearms license applicants will now be required to participate in state mandated safety training, which will include live fire exercises and “disengagement training.” Current license holders will be “grandfathered” into the new law and will not have to complete live fire training.

According to the Harvard Law Review, in the wake of Bruen, the state’s decision to include a live-fire requirement may have gone too far.

“Jurisdictions that require applicants for handgun carry licenses to complete a shooting qualification test need to furnish affirmative proof that conditioning the armed self-defense right on a scored live-fire exercise comports with the historical tradition of firearm regulation — no such tradition exists,” the legal review journal wrote.
