Firearm suppressors; creating the Sportsman Hearing Protection Act; providing requirements for manufacturing firearm suppressors in Oklahoma. Emergency.

SB 463, the "Sportsman Hearing Protection Act," exempts firearm suppressors manufactured entirely within Oklahoma from federal regulations, including registration requirements. It defines "manufactured in Oklahoma" as using only state-sourced basic materials (excluding generic parts like screws), requires "Made in Oklahoma" stamping on such suppressors, and directs the state Attorney General to seek federal court rulings on the exemption's constitutionality. The bill prohibits Oklahoma state and local entities from enforcing federal laws that regulate suppressors in ways inconsistent with this state law, and bans enforcement of conflicting federal rules by local officials or agencies. This law applies directly to suppressor manufacturers in Oklahoma and state/local government bodies.
