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

SB 557 expands Oklahoma's state preemption law for firearms to include "firearm and ammunition components," meaning local governments (cities, counties) cannot create their own rules about these parts. It prohibits municipalities from adopting policies or ordinances regulating firearm components, ammunition, or related supplies, overriding existing local laws. The bill clarifies legal procedures, allowing people to sue if local rules violate the preemption and recover attorney fees or court costs if they win. This law takes effect November 1, 2025.
