Assault weapons ban in New York politics
See also: Gun laws in the United States (by state)
The state of New York's version of the law is very similar to the Federal version, but New York's version does not have a sunset provision. According to the laws of the State of New York, a magazine with a capacity of more than 10 rounds manufactured after September 14, 1994 cannot be legally possessed by anyone other than a law enforcement officer. A provision of the Federal law required that gun makers stamp the date of manufacture on every newly manufactured 'large capacity' magazine. Because that requirement is no longer in effect, the New York magazine ban becomes potentially unenforceable, except with respect to those magazines manufactured during the ban and marked according to federal regulations then in effect.
NYS Penal Law § 265.02(6) makes it a class D felony to possess "a large capacity ammunition feeding device," which is defined in Penal Law § 265.00(23) as "a magazine, belt, drum, feed strip, or similar device, manufactured after [September 13, 1994], that has a capacity of, or that can be readily restored or converted to accept, more than ten rounds of ammunition." Possession of unmarked "large capacity" magazines made after the sunset of the federal ban thus subject New Yorkers to felony charges. Police and prosecutors may be able to determine actual manufacture dates of seized magazines from information not generally available to consumers, such as the dates of magazine design changes and parts assembly numbers. The New York ban thus leaves possessors of unmarked post-ban magazines at risk of felony charges since they may not know the magazines were manufactured post-sunset and not pre-ban. However, the prosecution must be able to prove that the subject in possession of the magazine had knowledge that it was in fact a post-ban magazine.
