New Jersey prohibits the manufacture, transportation, shipment, sale or disposal of any large capacity ammunition magazine, unless the magazine is intended to be used for authorized military or law enforcement purposes.1 In 2018, New Jersey redefined “large capacity ammunition magazine” as a box, drum, tube or other container which is capable of holding more than 10 rounds of ammunition to be fed continuously and directly into a semi-automatic firearm.2 Individuals who possess certain firearms with magazines capable of holding between 11 and 15 rounds of ammunition may register those firearms until July 13, 2019.3

The state prohibits the knowing possession of a large capacity magazine unless the possessor has registered an assault firearm pursuant to state law and uses the magazine in connection with competitive shooting matches sanctioned by the Director of Civilian Marksmanship of the U.S. Department of the Army.4
