Assault weapon sales in the United States, including the AR-15, have been on the rise, firmly establishing it as one of the country’s top firearms. Not all states endorse the possession of these kinds of firearms, however. Currently, ten states, along with Washington, D.C. have implemented bans on assault-style weapons. Washington recently became the 10th state to impose significant restrictions on these weapons.

This new law prohibits the sale, manufacture, import, and distribution of specific assault-style rifles, pistols, and shotguns. However, it’s important to note that the new law does not explicitly outlaw the possession of assault weapons and also permits Washington residents to inherit them legally or sell them to a federally licensed firearm dealer. Despite facing multiple legal challenges from gun rights advocates, efforts to block their implementation have been have been rejected by the courts.

Like other states with similar or even stricter laws, Washington’s recent legislation applies to a wide range of firearm models and specific features. These include semiautomatic rifles with detachable magazines that have a pistol grip, a folding stock, a barrel shroud, or a flash suppressor. The law also prohibits semiautomatic pistols with detachable magazines that have a secondhand grip, a threaded barrel, or a shrouded barrel. 

24/7 Wall St. determined the states that have banned assault-style weapons by analyzing data compiled by the Giffords Law Center, an organization advocating for gun control. Bans on assault weapons in the states on this list were typically put in place in an attempt to reduce mass shootings. Many of the deadliest mass shootings in recent years involved the types of firearms that are now banned in the states listed. 

Giffords reports that the federal government enforced an assault weapons ban from 1994 to 2004, during which time mass shooting fatalities were 70% less frequent compared to the periods before or after the ban. In several states on this list, bans on assault weapons have been in place for decades, some even predating the federal ban.
