Illegal, deadly firearms accessories just a click away in Mass. (wcvb.com)
BOSTON —
Massachusetts has some of the strictest gun laws in the country, but those laws are doing little to stop the purchase of firearms accessories that can be easily turned into illegal silencers or be used to turn certain handguns into machine guns.
The silencers are being sold as fuel filters or solvent filters and typically are shipped from China, according to David Magdycz, acting special agent in charge for Homeland Security Investigations in Boston.
But when investigators visit the homes where the fuel filters have been delivered, they have never found them to be used as anything but illegal silencers.
"We've found no legitimate use for these suppressors or these silencers, ever. We've never gone to a residence and had them show us exactly what they attach to or how they're used as an oil filter or a solvent filter," Magdycz said.
Trigger switches turn a Glock handgun from a semi-automatic firearm, which fires one bullet every time the trigger is pulled, into an automatic weapon, rapidly firing bullets with one pull of the trigger.
A machine gun is "incredibly dangerous," Magdycz said.
"We've had incidents where individuals have had a (legal) fully automatic weapon, and when they fire it, they don't know how to fire it. And it's gone out of control and killed people," he said. "On the street side, it's 100 percent illegal. You cannot, without the proper license, have a fully automatic weapon. It's dangerous for law enforcement. It's dangerous for other civilians, especially in these tumultuous times now. We're afraid that these items in the wrong hands would obviously prove more dangerous to everyone in the community."
