Regulations: Unique Serial Number Application (USNA) Process

These regulations create a unique serial number application process; one that every individual shall undergo if the individual owns a self-manufactured or self-assembled firearm or intends to manufacture or assemble a firearm. Through this process, the Department can allow those who are lawfully eligible to possess a firearm to retain their self-manufactured or self-assembled firearm while disarming prohibited persons who own a self-manufactured or self-assembled firearm. These regulations describe the mandatory reporting process the Department is putting into effect for the owner of a self-manufactured or self-assembled firearm, making it easy for such owners to report their firearms to the Department.
