There are federal laws outlined under the Gun Control Act of 1968 and the National Firearms Act that are prosecuted federally if they are broken. If you are using a firearm or other weapon across state lines, trafficking weapons in any way, or using a firearm after or during a federal felony conviction, then these crimes can be charged and processed on the federal level. It’s important to remember that other weapons offenses, such as illegal possession and use of a firearm, will be prosecuted under North Carolina state law.
