Under a new law, Massachusetts gun owners have until Wednesday, Jan. 31 to relinquish bump stocks, which allow rifles to be fired more rapidly.
In November, Massachusetts became the first state to make the possession of bump stocks illegal, about a month after a gunman in Las Vegas used one to kill almost 60 people.
The law also prohibits possession of trigger cranks, another accessory that allows someone to shoot faster.
When the bill passed, Karen Spilka, chair of the state Senate Ways and Means Committee, spoke about its importance.
"We are going after those devices -- those two devices that can make guns an almost automatic," Spilka said.
"This is something that, you know, the legislature wanted to do as a knee-jerk reaction," he said.
Wallace said his members are angry.
"Basically, what they're being told is that something that is an accessory -- and that they spent hundreds of dollars on -- is now contraband, and is outlawed within the state," he said. "It's one thing to ban something and then offer to pay for it. It's another to ban something and then demand that they turn it in without compensation."
The law also prohibits the sale or transfer of the banned items.
"A property tag will be filled out by our officers and a copy given to the person who turns it in," he said. "From there, they go to our evidence officers, and then we'll be in touch with the state to find out how they want them disposed of -- if they want it turned in there. That part we're not entirely sure of yet, but they will be stored in our department until the state gives us further instructions."
