Regardless of what some nameless person told a caller on the phone when asked, under 2C:39-1f, BB rifles and pistols ARE considered firearms in this G-d forsaken state.
" f. "Firearm" means any handgun, rifle, shotgun, machine gun, automatic or semi-automatic rifle, or any gun, device or instrument in the nature of a weapon from which may be fired or ejected any solid projectable ball, slug, pellet, missile or bullet, or any gas, vapor or other noxious thing, by means of a cartridge or shell or by the action of an explosive or the igniting of flammable or explosive substances. It shall also include, without limitation, any firearm which is in the nature of an air gun, spring gun or pistol or other weapon of a similar nature in which the propelling force is a spring, elastic band, carbon dioxide, compressed or other gas or vapor, air or compressed air, or is ignited by compressed air, and ejecting a bullet or missile smaller than three-eighths of an inch in diameter, with sufficient force to injure a person. "
So to paraphrase a well-hated Socialist Senator from Kalifornia:
"Ladies and gentlemen, boy and girls, TURN THEM IN !!!!!!"
