Where Are Assault-Style Weapons Illegal? The 10 States With Bans

Each state in the US has its own gun laws and restrictions, with some much less stringent than others. There are only 1o states in the country that ban assault weapons. However, note that each state may have a varying definition of the definition of an assault weapon with no universally agreed upon definition. In general, assault weapons are military-style semi-automatic firearms with certain features like a bayonet mount or telescoping stock.

Using data compiled by the 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.

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.
