(b)(1) Subsection (a) does not affect the authority a municipality has under law to regulate the discharge of firearms within the limits of the municipality or the authority a county has under law enacted prior to August 1, 2000, to regulate the discharge of firearms within the jurisdiction of the county.
(2) Subsection (a) does not affect the authority of the state, a county, or a municipality to assess, enforce, and collect sales taxes, use taxes, and gross receipts taxes in the nature of sales taxes as defined by Section 40-2A-3(8), on the retail sale of firearms and ammunition or to assess, enforce, and collect business licenses from firearms or ammunition manufacturers, trade associations, distributors, or dealers for the privilege of engaging in business.
