No. The law as written is protection from targeted zoning that would prevent them from opening a firearms business. They still have to comply with the same zoning that any other business would need.let try it this way:
The FFL exempts them from zoning.
BUT they still need to deal with the noise issues of the range.
They are trying to operate a commercial business on property that is zoned as agricultural. Getting an FFL does not provide them an exemption from meeting the same requirements as any other business.
Commercial zoning holds businesses to a different set of standards. Getting an FFL does not exempt a business from those standards. It means they can’t be discriminated against.
