context_page_description: Bump stocks or bump fire stocks are gun stocks that can be used to assist in bump firing. Bump firing is the act of using the recoil of a semi-automatic firearm to fire ammunition cartridges in rapid succession, but with a loss of accuracy.
  The legality of bump stocks in the United States came under question following the 2017 Las Vegas shooting, which left 59 civilians dead and an additional 868 injured; the gunman was found to have equipped them to his weapons. Several states passed legislation restricting ownership of bump stocks following this shooting and the one at Marjory Stoneman Douglas High School months later, and the U.S. Justice Department banned them at the federal level in December 2018.
context_section_description: Prior to the federal ban effective March 26, 2019, some states had taken action on their own to restrict ownership of the accessory. Since 2002, the sale of bump stocks has been illegal in California. They were banned in New York with the passage of the NY SAFE Act in 2013, and more explicitly banned in early 2019. The device's legal status is unclear in Connecticut, Michigan, Minnesota, and Puerto Rico.
