Go online and you can buy up to 80 percent of parts of a gun. Considering it's not assembled and only part of a gun, it's not considered one in the eyes of federal law.

It's a major loophole that's leading to "ghost guns" becoming more common.

"You get 80 to 85 percent of the gun, it is not a quantum leap in logic to be able to finish off that product with legally available tools in New York and give yourself an operable gun," said Onondaga County District Attorney William Fitzpatrick.

The term "ghost gun" is simple: it's a gun bought online, assembled at home and without a serial number. These guns aren't traceable, leading to many issues for law enforcement.

"We have incidents, where we recovered in crimes, over two dozen ghost guns," said Fitzpatrick. 

"Ghost guns" are found right here in Onondaga County — most used in crimes, like the Fenton Street shooting in Syracuse where a 6-year-old was shot by a "ghost gun."

"What the governor is proposing is to make the seller on the other end of it a lawbreaker as well," said Fitzpatrick.

Gov. Andrew Cuomo is proposing new legislation to prevent sales of these guns in the state.

"We're not looking to prosecute more people, we're looking to de-incentivize people from selling in New York," said Fitzpatrick.

The proposal would require that firearm parts only be sold to authorized buyers. It would also require the same eligibility requirements as a completed firearm and that all major parts receive a serial number.

"Some entrepreneurs have looked at it and said, ‘Look, we're not violating the federal statute, let's do it.’ That's kind of callous isn't it?" asked Fitzpatrick. 

It’s already a felony to buy parts of a gun, assemble it, and not register that gun.

"I think it will be very effective. I don't know any lawful businessman or woman involved in that business who won't say, 'OK, I won't sell in New York,'" said Fitzpatrick.

The proposed legislation is slated to be a part of the governor's State of the State address.
