This bill proposes significant amendments to New Jersey's firearm laws, particularly focusing on the definitions and regulations surrounding ammunition magazines. A key change is the deletion of the definition of "large capacity ammunition magazine," which previously referred to magazines capable of holding more than 10 rounds. The bill also removes the requirement that semi-automatic shotguns with a pistol grip or folding stock must have a magazine capacity exceeding six rounds to be classified as "assault firearms." By eliminating these restrictions, the legislation aims to broaden the scope of permissible firearms and ammunition configurations in the state.

In addition to the changes regarding magazine capacity, the bill introduces new regulations concerning the possession of bump stocks, trigger cranks, and firearms without serial numbers, establishing penalties for violations that range from third to fourth degree crimes. It also imposes stricter penalties for the manufacturing and distribution of firearms, particularly those made using three-dimensional printing technology, classifying unauthorized manufacturing as a second-degree crime. The bill emphasizes the importance of maintaining records for the sale and transfer of firearms and ammunition, particularly in relation to law enforcement. Overall, the legislation reflects a significant shift in New Jersey's approach to firearm regulation, enhancing public safety while streamlining existing laws.
