Prohibit the sale and possession of ghost guns
SF3661 would create a new set of Minnesota laws aimed at restricting so-called ghost guns and other unserialized firearms. The bill defines a “ghost gun” broadly to include firearms, frames, or receivers without a unique serial number, firearms that are undetectable by metal detectors or easily made so, and firearms made by 3D printers or CNC milling machines by people who are not federally licensed manufacturers. It makes it a crime to possess, sell, transfer, or distribute ghost guns, and it also criminalizes altering or removing serial numbers.
The bill also regulates home assembly and manufacturing of firearms. It would limit non-licensees to assembling or manufacturing no more than three firearms per calendar year, require anyone making a firearm without a serial number to obtain one from a federal firearms licensee, and require the firearm to be serialized within ten days. It further prohibits non-licensees from manufacturing firearms with 3D printers or CNC milling machines and bars the distribution of digital design files used to print ghost guns. A separate section sets detailed requirements for federal firearms licensees that apply serial numbers, including recordkeeping and public notice by the commissioner of public safety. The bill repeals the existing Minnesota statute on removal or alteration of firearm serial numbers and replaces it with broader ghost-gun and serialization provisions.
If enacted, the bill would significantly expand state firearms regulation by creating new criminal offenses and compliance duties for gun owners, hobbyists, sellers, and federal firearms licensees. It would affect possession of unfinished frames and receivers, inheritance and relocation situations involving unserialized firearms, and the handling of 3D-printed or otherwise privately manufactured guns. It also gives law enforcement and the Department of Public Safety new enforcement and public-notice responsibilities.
The general sentiment reflected by the bill text and caption is strongly supportive of gun-control measures focused on public safety and preventing untraceable firearms from circulating in the state. No committee transcript or vote record is provided, so there is no recorded debate or roll-call evidence here to indicate broader legislative support or opposition. Based on the structure and scope of the bill, the likely policy emphasis is on tracing firearms, preventing illegal manufacture, and limiting access to ghost-gun technology.
The main points of contention likely involve Second Amendment concerns, regulation of home gunsmithing, the three-gun annual limit for non-licensees, and restrictions on digital firearm design files. Gun owners, hobbyists, and civil-liberties advocates may object to the breadth of the definitions and the criminal penalties, while supporters would likely argue the bill closes loopholes that allow untraceable weapons to evade existing firearm laws.
The bill would add new sections to Minnesota Statutes chapter 624 governing ghost guns, firearm serialization, and private manufacture, while repealing Minnesota Statutes 2024, section 609.667 on removal or alteration of serial numbers. It would create new criminal penalties for possession, sale, transfer, distribution, manufacture, and alteration of unserialized or ghost guns, and impose serialization and recordkeeping duties on federal firearms licensees. It also requires the Department of Public Safety to issue a public notice and classifies related serial-number data under Minnesota data practices law.
The bill’s overall tone is pro-regulation and public-safety oriented, with the caption and provisions indicating a clear intent to prohibit ghost guns and limit untraceable firearm production. Because no committee discussion or votes are included, there is no direct evidence of bipartisan support, organized opposition, or amendments. The available record suggests a policy approach designed to strengthen enforcement and close perceived loopholes in firearm identification and manufacture.
The most likely areas of contention are the criminalization of possession of unserialized firearms, the requirement that existing owners and new residents serialize or remove such firearms within short deadlines, and the ban on non-licensees using 3D printers or CNC milling machines to make firearms. Another likely dispute is the prohibition on distributing digital design files for printing ghost guns, which raises free-speech and technology-regulation concerns. Supporters would likely emphasize traceability and crime prevention, while opponents may argue the bill burdens lawful hobbyists, inherited firearms, and private firearm construction.
