Unserialized firearms ("ghost guns"); create crime of possession of.

HB 434 creates a new crime for possessing an unserialized firearm or unserialized unfinished frame/receiver (commonly called a "ghost gun") unless the person is a licensed federal firearms dealer, manufacturer, or importer. The bill requires firearms made using 3D printing technology to be serialized (marked with a unique identifier) by August 1, 2026, or before they become functional. Starting January 1, 2027, it becomes illegal for most individuals to possess such unserialized items, with limited exceptions for licensed businesses. The law defines key terms like "unserialized" and "unfinished frame" to clarify the scope of the new offense.
