North Carolina is a Common Law Jurisdiction.
In other words..., '... that which is NOT Prohibited is Allowed.'
North Carolina ONLY Bars Carrying a Concealed Weapon, per NC GS 14-269.
In North Carolina..., getting a Valid North Carolina Concealed Weapons Permit ONLY Authorizes an additional option for Carry, via., Concealed Carry.
One needs no Permit to Openly Carry a Firearm, or any other Weapon, in North Carolina, so as long as the Firearm or Weapon is Possessed by a Law-abiding Person and that the Person is not in a Prohibited Area.
Article 35, of Chapter 14, spells out those Prohibitions.
North Carolina General Statute 14-409.40 enacts Preemption of Firearm-related matters, whereby; such Preemption Precludes the Enforcement of any Open Carry Bans, not in conformity to General Statutes enumerated under Article 35 of Chapter 14, or where otherwise Prohibited by Law.
P.S.: By way of a North Carolina CCW, one opens Himself to a entirely new set of Regualtions under Artilce 54B, of Chapter 14.
