TYPES OF ITEMS REGULATED UNDER THE NATIONAL FIREARMS ACT
The National Firearms Act (NFA) regulates various weapons by imposing registration requirements and a special tax on those items. However, most legal gun owners in the United States can absolutely own these items, as long as the individual state laws and application procedures are properly followed.
