Assault weapon deadline arrives – New Yorkers are required to register their assault weapons under the state’s new gun-control law today — or face time behind bars.  Today is the deadline for state residents who own guns labeled as assault weapons under the New York SAFE Act to register them with the state. Assault weapons are those with a “military-style feature” such as a detachable magazine, pistol grip or telescoping stock.  If gun owners fail to register their firearms today, they could be charged with a class A misdemeanor and spend up to a year in county jail. If an individual unintentionally fails to register, a 30-day amnesty period will be extended, according to the New York State Police.
