Under United States federal law, machineguns are restricted under the [[National Firearms Act]] and other laws. Beginning in 1982, the [[ATF]] started classifying some open bolt firearms as machineguns, namely the [[KG-9]] pistol,<ref>{{Cite web |date=January 19, 1982 |title=1982-2 - KG-9 Pistol as NFA Weapon |url=https://www.atf.gov/firearms/docs/ruling/1982-2-kg-9-pistol-nfa-weapon/download |archive-url=https://archive.today/20230531234045/https://www.atf.gov/firearms/docs/ruling/1982-2-kg-9-pistol-nfa-weapon/download |archive-date=May 31, 2023 |access-date=May 31, 2023 |website= |publisher=[[ATF]]}}</ref> [[Ingram M10|SM-10]] pistol, [[Ingram MAC-11|SM-11A]] pistol, SAC Carbine,<ref>{{Cite web |date=June 21, 1982 |title=1982-8 - SM10, SM11A Pistols and SAC Carbines as NFA Weapons |url=https://www.atf.gov/firearms/docs/ruling/1982-8-sm10-sm11a-pistols-and-sac-carbines-nfa-weapons/download |archive-url=https://archive.today/20230531234345/https://www.atf.gov/firearms/docs/ruling/1982-8-sm10-sm11a-pistols-and-sac-carbines-nfa-weapons/download |archive-date=May 31, 2023 |access-date=May 31, 2023 |website= |publisher=[[ATF]]}}</ref> and the YAC [[Sten|Sten MK II]].<ref>{{Cite web |title=1983-5 - STEN MK II as NFA Weapon |url=https://www.atf.gov/firearms/docs/ruling/1983-5-sten-mk-ii-nfa-weapon/download |archive-url=https://archive.today/20230531234939/https://www.atf.gov/firearms/docs/ruling/1983-5-sten-mk-ii-nfa-weapon/download |archive-date=May 31, 2023 |access-date=May 31, 2023 |website= |publisher=[[ATF]]}}</ref> Around the time of these rulings, the manufacture of new open-bolt semi-automatic firearms became uncommon in the United States. The open bolt semi-automatic versions of certain guns are often as costly as their fully automatic counterparts since, prior to the [[Hughes Amendment]], many such guns were lawfully converted into machineguns.<ref>{{Cite web|date=2013-06-20|title=Gun Review: "Open Bolt" Explained - A Tale of Two Uzis -|url=https://www.thefirearmblog.com/blog/2013/06/20/open-bolt-explained-tale-uzis/|access-date=2021-01-11|website=The Firearm Blog|language=en-US|archiveurl=https://web.archive.org/web/20221201202628/https://www.thefirearmblog.com/blog/2013/06/20/open-bolt-explained-tale-uzis/|archive-date=December 1, 2022}}</ref> However, there are many open-bolt firearms, that are not classified as [[machine gun]]s. The [[Demro TAC-1|Fox Carbine]] is one such example of an open-bolt firearm that was ruled to not be a machine gun.<ref>{{Cite web |date=May 3, 1974 |title=Fox Carbine ATF Letter |url=http://foxcarbine.com/images/ClassificationLetter.pdf |archive-url=https://web.archive.org/web/20170401031728/http://foxcarbine.com/images/ClassificationLetter.pdf |archive-date=April 1, 2017 |access-date=May 31, 2023 |website= |publisher=[[ATF]] |via=FoxCarbine.com}}</ref>
