Senate Bill No. 124 establishes new regulations regarding firearm suppressors in Oklahoma. It defines key terms such as "firearm suppressor," "generic and insignificant part," and "manufacture." The bill stipulates that firearm suppressors manufactured and remaining within the state are exempt from federal laws and regulations, including registration requirements. Additionally, it mandates that any suppressor produced in Oklahoma must be clearly marked with "Made in Oklahoma." The bill also clarifies that basic materials used in the manufacturing process are not considered firearm suppressors and thus are not subject to federal regulation.

Furthermore, the bill prohibits any agency, municipality, or political subdivision from enacting rules or regulations that would impose restrictions on firearm suppressors that are not already established by state law. This aims to ensure uniformity in the regulation of firearm suppressors across the state. The act is set to take effect on November 1, 2025.
