N.C. Gen. Stat. § 14-7.36
Any person who has been convicted of or pled guilty to one or more prior firearm-related felony offenses in any federal court or state court in the United States, or combination thereof, is guilty of the status offense of armed habitual felon and may be charged with that status offense pursuant to this Article.
This Article does not apply to a second firearm-related felony unless it is committed after the conviction of a firearm-related felony in which evidence of the person's use, display, or threatened use or display of a firearm was needed to prove an element of the felony or was needed to establish the requirement for an enhanced or aggravated sentence. For purposes of this Article, firearm-related felonies committed before the person is 18 years of age shall not constitute more than one firearm-related felony. Any firearm-related felony to which a pardon has been extended shall not, for the purposes of this Article, constitute a firearm-related felony.
