"It doesn't have a compensator, and it doesn't have a pistol grip," explained Marvin Vann, demonstrating one of the guns he converted.
He did it because guns classified as assault weapons are banned under the SAFE Act. If you already owned one before the law took effect, you can keep it, but you have to register it with the state by Tuesday, April 15.
"Most of them aren't going to register," Vann said. While he fully complies with the law, he says many of the customers at his Plattsburgh store have concerns.
"Registration is the first step to take your guns away from you," he said.
Registration is free, and can be done on the SAFE Act website. There's an interactive tool that lets you know if your gun falls under the assault weapon criteria. But regardless of convenience, many gun owners are not jumping on board.
"I do have weapons that would be considered assault weapons under the law," said Andy Peda, a gun owner from Plattsburgh.
"Have you registered them?" we asked Peda.
"Do you plan to?"
"I'm still debating," he said. Peda says he is not too worried about what will happen if he doesn't register.
"You can't arrest the whole state, everyone who owns them, in one shot."
Gun owners who are caught with an unregistered assault weapon can be arrested and charged with a misdemeanor, and run the risk of having their gun taken away.
New York State Police said a confidentiality clause in the Safe Act prevents them from releasing how many people have currently registered assault weapons.
