Firearms; expanding scope of certain state preemption. Effective date.

SB 557 expands Oklahoma's state preemption law to include firearm and ammunition components (like magazines or parts), meaning local governments cannot pass rules about these items. It prohibits cities or counties from adopting policies, ordinances, or resolutions that conflict with state firearms law, including restrictions on components. The bill clarifies legal procedures for challenging local rules that violate preemption, allowing affected individuals to sue for damages or court costs and requiring local entities to give 90 days to fix violations before legal action. It also defines "reasonable expenses" to cover attorney fees in such cases. This law directly affects local governments and residents by preventing municipal regulations on firearm components.
