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, preventing local governments from regulating these items. The bill prohibits municipalities from enacting rules on the sale, possession, transportation, or other controls of firearms, knives, ammunition, and these new components, except for limited ordinances about firearm discharge, transportation citations (with penalties capped at Oklahoma Self-Defense Act levels), and air-powered pistol/rifle discharge on property. Individuals can sue local governments for violating this preemption and recover reasonable legal expenses if the local law isn't rescinded within 90 days after written notice.
