Minnesota Advances Semi-auto Firearm Ban Allowing Warrantless Home Inspections of Gun Owners

Minnesota lawmakers are advancing legislation that would ban possession of nearly every semiautomatic firearm in the state, creating what gun rights advocates warn constitutes one of the nation’s most aggressive attempts to criminalize commonly owned weapons while imposing unprecedented warrantless home inspections on gun owners who attempt to comply.

House File 3433 and its Senate companion SF 3654, introduced by DFL legislators in the 2026 Minnesota legislative session, carry the title “Possession of semiautomatic military style assault weapons banned, and criminal penalties provided.” The measures are part of a broader gun control package that includes companion bills and separate magazine capacity restrictions.

As of February 22, 2026, the bills were referred to the House Public Safety Finance and Policy Committee, with a hearing scheduled for February 24, 2026. The Minnesota Gun Owners Caucus reported that the Senate versions were not moving as of that date, though the political dynamics remain precarious.

The legislation dramatically expands Minnesota’s existing statutory definition of a “semiautomatic military style assault weapon” to cover semiautomatic rifles that accept a detachable magazine and have one or more features including pistol grips, adjustable or telescoping or thumbhole stocks, flash suppressors, barrel shrouds, threaded barrels, or forward grips. Any semiautomatic centerfire or rimfire rifle with a fixed magazine holding more than 10 rounds would also be banned, along with semiautomatic pistols with detachable magazines and specific features, shotguns with various characteristics, and parts or conversion kits from which such weapons could be assembled.

The Minnesota Gun Owners Caucus bluntly summarized the scope, stating this covers “basically, almost every single semiautomatic rifle.” The bill makes it unlawful to transfer, own, or possess any firearm meeting the new definition. Violations would be a felony punishable by up to five years in prison and a $25,000 fine.

A limited grandfathering provision exists for firearms lawfully owned before January 1, 2027, but the conditions are extraordinarily restrictive. Owners must apply for a state issued certificate of ownership from the Bureau of Criminal Apprehension by May 1, 2027, at an unspecified fee. They must allow warrantless law enforcement inspections of their homes to verify “safe storage” compliance with no limit on frequency. They must renew the certification every three years. Also, they can only possess the firearm on property they own or control or at a licensed firing range. They must report loss or theft within 48 hours. Most significantly, no transfers whatsoever are permitted, not even to family members, not through a trust, and not through inheritance.

Anyone who doesn’t go through the certification process must, by January 1, 2027, surrender the firearm for destruction, permanently disable it, or remove it from the state.

Because the firearm can only be kept at home or at a licensed firing range, hunting with a grandfathered firearm is effectively prohibited since owners cannot transport it to hunting land. The bill also effectively bans all future purchases of covered firearms within the state.

The Minnesota Gun Owners Caucus, chaired by Bryan Strawser, has led in state opposition. The organization argues the ban directly violates the Second Amendment’s “common use” standard established in District of Columbia v. Heller and reinforced in New York State Rifle & Pistol Association v. Bruen, which holds that the government cannot ban firearms “commonly owned for lawful purposes.” Semiautomatic rifles are among the most commonly owned firearms in America.

Minnesota Gun Owners Caucus member Sarah Hauptman testified before lawmakers that “normal people should not become felons for owning normal things.”

The Caucus identifies the warrantless inspection requirement as a blatant Fourth Amendment violation. The organization frames the legislation as outright confiscation, noting that the only options for noncompliant owners are surrender, destruction, or removal from the state. They argue criminals will ignore the law, and only law abiding citizens will be punished.

Strawser warned that the DFL controls the Minnesota Senate by one vote, no DFL Senator is pro-gun, and the House is tied, meaning only one Republican defection could pass the bill.

🚨 HAPPENING NOW 🚨

Hundreds of you have already submitted written testimony opposing HF 3433 (Gun Ban) and HF 3402 (Magazine Ban).

That’s great.

But there are hundreds of thousands more of you who still need to act before 3:00 PM today.

As of February 23, 2026, HF 3433 is scheduled for a committee hearing on February 24 in the House Public Safety Finance and Policy Committee. Whether the bill advances depends heavily on whether DFL leadership can hold all their members and flip at least one Republican in the evenly divided House. By demanding warrantless home inspections with unlimited frequency as the price of retaining lawfully purchased property, Minnesota lawmakers have transformed constitutional rights into revocable government privileges. The surveillance regime violates both the Second and Fourth Amendments while doing nothing to disarm the criminals who ignore such laws entirely.
