Purpose

This bill would ban possession of semiautomatic militarystyle assault weapons and large-capacity magazines in Minnesota, and it would create criminal penalties for violations. It also changes and adds definitions in Minnesota’s gun laws to implement and enforce this ban.

Main provisions

  • Prohibition on possession
    • The bill prohibits possessing semiautomatic militarystyle assault weapons (SMAWS). A weapon is considered an SMAW if it falls into specific model types or if it has certain features that make it militarystyle.
    • It includes a long list of firearm models and types (for example, certain AK-47-type rifles, AR-type rifles, MAC-10/MAC-11, TEC-9, Uzi, Steyr AUG, and multiple other named rifles/pistols) and also covers rifles and pistols that are manufactured by another company under a licensing agreement to be identical or nearly identical to those listed.
    • It also covers firearms that are redesigned, renamed, or renumbered versions of these listed firearms, or that have minor modifications such as a folding stock, adjustable sights, different calibers, bayonet mounts, or other features that make them similar in action design.
    • The bill notes that some of these weapons were previously barred from importation by federal authorities (BATF) and clarifies that permanently inoperable firearms are not considered SMAWs.
  • Definitions and scope of SMAW
    • SMAW includes not only named models but also firearms that can accept a detachable magazine and have one or more qualifying features (pistol grips, thumbhole stocks, folding/ telescoping stocks, shrouds around the barrel, flash suppressors, or other features that enable use with a non-trigger hand).
    • It also includes semiautomatic pistols or rifles with fixed or detachable magazines that have more than ten rounds, and pistols with certain additional features (grip, stock types, shrouds, threaded barrels, etc.).
    • The definition explicitly covers semiautomatic shotguns with certain features (pistol grips, folding/ telescoping stocks, large-capacity or detachable magazines) and shotguns with revolving cylinders or conversion kits capable of assembling SMAWs.
  • Large-capacity magazines
    • The bill defines “large-capacity magazine” as any feeding device that can hold more than ten rounds, or parts that enable assembly of such a device, when in possession or control of the same person.
    • It provides exceptions: permanently altered devices that can only hold ten or fewer rounds; certain .22 caliber tube feeding devices; and tubular magazines in lever-action firearms.
  • Amendments to Minnesota Statutes
    • The proposal would add and modify specific Minnesota Statutes (including sections cited in the bill) to codify the new prohibition and definitions and to create penalties for violations.
    • It references adding new subdivisions and sections to Chapter 624 to implement these prohibitions and definitions, along with cross-references to other related sections.

Significant changes to existing law

  • New ban on possession of semiautomatic militarystyle assault weapons, with a detailed, enumerated list of included models and feature-based criteria.
  • New, explicit definition of large-capacity magazines (>10 rounds) and specified exemptions.
  • Creation of new statutory subdivisions and sections within Minnesota’s gun laws to enforce the SMAW ban and large-capacity magazine prohibition, including penalties for violations.
  • Clarification that certain firearms that are permanently inoperable are not considered SMAWs.
  • Incorporation of historical importation restrictions and licensing concepts into the scope of the new prohibitions.

Potential implications

  • Owners of the listed firearms or any firearm matching the described features could be subject to penalties if they possess SMAWs or large-capacity magazines.
  • The law would require firearm owners and dealers to assess whether a firearm or magazine falls under the SMAW or large-capacity definitions.
  • Law enforcement and courts would apply the new definitions and penalties in enforcing possession restrictions.
