Firearms; expanding scope of state preemption provision to include firearm and ammunition components; emergency.

HB 2820 expands Oklahoma's state preemption law to include firearm and ammunition components (such as magazines or parts), meaning local governments cannot regulate these items. It prohibits cities or counties from enacting rules about the sale, possession, or use of firearm components, overriding any existing or future local ordinances on these topics. Limited exceptions remain for local rules about discharging firearms, improper firearm transport citations (with penalty limits), and air-powered weapons. The bill directly affects residents who own or use firearm components and local governments trying to implement related restrictions. It does not change existing state laws on firearms, ammunition, or the limited local rules permitted under the bill.
