The New York City Police Department recently mailed 500 letters to registered owners of shotguns and rifles that can hold more than five rounds.
The letter told these gun owners that their long guns are violating a 2010 New York City law.
According to TheTruthAboutGuns.com, the Nov. 18 letter tells gun owners to surrender their rifle and/or shotgun to a local police precinct or prove their guns have been moved out of New York City or have their gun altered by a licensed gunsmith.
"We think it's an abuse of power by the NYPD," Tom King, of New York State Rifle & Pistol Association, told Fox News.

"A gun collector who never fired a gun in his life, but has a few antiques might have to get them altered," added King. "These are not the people law enforcement should be targeting."
"These letters appear to be another example of the Nanny State," said New York State Assemblyman James Tedisco. "Hypothetically, it can start with a letter, and then that can lead to someone knocking on your door saying, 'I want to see your gun.'"
In a report earlier this year, The Center for American Progress claimed that "many of the states with the weakest gun laws also have the highest levels of gun violence."
