Seems pretty outlandishly broad and infringy...

(Ord. 1304 NCS §6, 1978.)
BTW, slingshots are considered “firearms” per this ordinance...
By this same reasoning, just to give one example, a wood-burning stove is illegal because it "fires", and "throws or projects bullets or missiles of any kind to any distance by means of elastic force, air or any explosive substance". Ever see a knot of pitch fire while a log is burning? And what about all those sparks then? Those are projectiles, under the same definition that bullets are.
I really should not expound about how a mortar could be legally argued as not falling under this definition as well...
How does one fire or discharge an anvil?
Did this person who wrote this get his degree through the Looney Toons School of Law?
