Editing Flash suppressor (section)

===United States===
Flash suppressors were seen as "military" features and were on the list of federally defined features that could cause a rifle to be defined as illegal if the lower receiver was manufactured after the effective date of the [[Federal Assault Weapons Ban]] that went into effect in 1994 in the United States.<ref>{{cite journal |title=Endangered Tradition |last=Petzl |first=David |pages=26–30 |journal= Field & Stream |year= 1994 |volume=99|issue=2}}</ref> This ban expired in 2004, although some states, such as [[California]], [[Massachusetts]], [[Maryland]], [[New York (state)|New York]], and [[New Jersey]], have similar bans in place restricting the use of flash suppressors.<ref name=awguide>[http://oag.ca.gov/sites/all/files/pdfs/firearms/forms/awguide.pdf "Assault Weapons Identification Guide"] {{Webarchive|url=https://web.archive.org/web/20131213160751/http://oag.ca.gov/sites/all/files/pdfs/firearms/forms/awguide.pdf |date=2013-12-13 }}, California Department of Justice.
