Bill Overview
Analyzed Economic Effects
6 provisions identified: 1 benefits, 4 costs, 1 mixed.
Penalties and 2027 start for violations
Beginning January 1, 2027, penalties apply for serial‑number violations. A first unlawful possession is a civil fine up to $50. A second possession offense is a Class D crime; a third or later is a Class C crime. For unlawful import, transfer, offer to transfer, or purchase, the first offense is a Class D crime and later offenses are Class C crimes. Using an unnumbered item during a Class A or B crime or reckless conduct is a Class C crime.
Serial numbers required on guns and parts
Beginning January 1, 2027, unfinished frames and receivers count as firearms under state law. You may not possess, import, sell, or transfer a firearm, frame, or unfinished frame unless a federal firearms licensee (FFL) has imprinted a serial number under federal law or section 2039. This applies to do‑it‑yourself builds and core parts, not just complete guns.
FFL serial-numbering duties and penalties
FFLs may imprint serial numbers and must keep records. At scheduling, an appointment record must be made, a confirmation given, and the record kept at least 30 days. Imprint records must include the date, transferee’s name, age, residence, and the serial number. The serial must start with the FFL’s first 3 and last 5 license digits, a hyphen, and a unique ID, and follow federal size/depth rules. Imprinting alone does not make the FFL a manufacturer. Anyone who makes a frame or receiver, including with a 3D printer or CNC mill, must have an FFL imprint a serial number. Failing to make or keep required records is a civil fine up to $250 for a first offense, up to $500 for a second, and a Class E crime for a third or later.
Undetectable guns banned in Maine
It is illegal to make, import, sell, transfer, or knowingly possess an undetectable firearm in Maine. Making, importing, selling, or transferring one is a Class C crime. Knowing possession is a Class D crime.
Narrow exceptions for antiques, police, imprinting
Some people and situations are exempt. Examples include FFLs acting within their license, law enforcement uses, and transfers only to get a serial number imprinted. You may hold an unfinished frame or receiver for up to 48 hours if you have a scheduled FFL imprinting appointment. Antique firearms, curios or relics, permanently inoperable guns, and guns made before 1968 are also exempt as defined by law.
Background checks and rules for transfers
You must pass a federal background check to buy any frame or receiver. When an FFL returns a firearm, frame, or receiver after imprinting, that return counts as a transfer and needs a background check. If the check is denied, the FFL must deliver the item to law enforcement and get a receipt. A dealer may return an imprinted item to the same person it came from without a new background check if the imprinting followed federal law or section 2039 and the return is to the same person.
