Assault Weapons Are Legally Banned In These 10 States

Researchers are examining gun-control policies in the wake of a church shooting in Minnesota. They found evidence that some legislation, like assault-style weapon bans and high-capacity magazine limits, can reduce certain types of firearm deaths. For example, states with stricter laws tend to see fewer gun fatalities, and red-flag laws and child-access safe-storage laws are associated with reductions in suicides and accidental shootings. At the same time, because laws vary significantly by state, researchers struggle to isolate the independent impact of each policy, and even the strongest state-level measures are constrained by factors like weapons crossing state lines.

The increasing popularity of modern sporting rifles (MSRs) in the United States has sparked strong debates about gun control and public safety. Between 2013 and 2022, over 32.9 million MSRs were manufactured in the U.S. The National Shooting Sports Foundation reported that nearly 70% of MSRs in circulation since 1990 were sold in just the past 10 years.

MSRs are civilian firearms built on the platform of military rifles, like the AR-15 or AK-47. Controversial not only for their association with military applications, MSRs and other assault-style weapons have also emerged as a common denominator in mass shootings across the country. According to the gun control advocacy group Giffords Law Center, assault weapons were used to perpetrate each of the seven deadliest mass shootings in the U.S. in the last decade. As such, many states have banned these weapons.

Using data compiled by Giffords Law Center, 24/7 Wall St. identified the 10 states that have banned assault-style weapons. In addition to regulating assault weapons, the 10 states on this list have all imposed a range of restrictions that widely expand on federal gun control policy. Across these states, additional firearm regulations include universal background checks, mandatory waiting periods, high-capacity magazine bans, and permit and licensing requirements. (These are the states with the strongest and weakest gun control policies.)

Why It Matters

Gun control has long been a hot-button issue in American politics, and it remains so today. According to a June 2024 report from public opinion research company Morning Consult, 59% of American voters cite gun policy as a very important issue for the upcoming presidential election. Lately, the gun policy debate has centered largely around assault weapons, which are proven to be far deadlier than other firearms in active shooter scenarios. While most of the country has adopted a hands-off approach to regulating assault weapons, several states enacted laws that effectively prohibit these military-style firearms.
