Clarifies that BB guns are not firearms under New Jersey law.

This bill amends New Jersey's definition of "firearm" to explicitly clarify that BB guns are not considered firearms under state law. It directly affects recreational BB gun owners, manufacturers, and retailers by removing these devices from firearm regulations. The key provision updates the legal definition to exclude air guns using compressed air or CO2 to fire .177-caliber pellets at under 500 feet per second. This change prevents misclassification of BB guns under firearm laws, ensuring they are not subject to firearm licensing, registration, or possession restrictions.
