Editing Mosin–Nagant (section)

===Civil War, modernization, and wars with Finland===
During the [[Russian Civil War]], infantry and dragoon versions were still in production, though in dramatically reduced numbers. The rifle was widely used by all belligerents in the civil war. In 1924, following the victory of the [[Red Army]], a committee was established to modernize the rifle, which had by then been in service for over three decades. This effort led to the development of the Model 91/30 rifle, which was based on the design of the original dragoon version. The barrel length was shortened by {{convert|7|cm|in|abbr=on}}. The sight measurements were converted from [[Obsolete Russian units of measurement#Length|arshins]] to meters; and the front sight blade was replaced by a hooded post front sight less susceptible to being knocked out of alignment. There were also minor modifications to the bolt, but not enough to prevent interchangeability with the earlier Model 1891 and the so-called "Cossack dragoon" rifles.

[[Grand Duchy of Finland|Finland was a Grand Duchy]] in the Russian Empire until 1917, so Finns had long used the Mosin–Nagant in service with the Imperial military. The rifle was used in the short [[Finnish Civil War]] and adopted as the service rifle of the new republic's army. Finland produced several [[#Finland|variants]] of the Mosin–Nagant, all of them manufactured using the receivers of Russian-made, American-made, French-made or (later) Soviet-made rifles. Finland also utilized a number of captured M91 and M91/30 rifles with minimal modifications. As a result, the rifle was used on both sides of the [[Winter War]] and the [[Continuation War]] during World War II. Finnish Mosin–Nagants were produced by [[SAKO]], Tikkakoski, and VKT, with some using barrels imported from Switzerland and Germany. In assembling M39 rifles, Finnish armorers reused "hex" receivers that dated back as far as 1891. Finnish rifles are characterized by Russian, French or American-made receivers stamped with a boxed SA, as well as many other parts produced in those countries and barrels produced in Finland, Switzerland, Austria, Belgium and Germany. The Finns also manufactured two-piece "finger splice" stocks for their Mosin–Nagant rifles.<ref>{{cite web |url=http://www.rawles.to/Pre-1899_FAQ.html |title=The Pre-1899 Antique Guns FAQ |website=Rawles.to |access-date=7 June 2011 |url-status=live |archive-url=https://web.archive.org/web/20110514032921/http://www.rawles.to/Pre-1899_FAQ.html |archive-date=14 May 2011}}</ref>

In addition, the rifle was distributed as aid to [[Second Spanish Republic|Republican]] anti-[[Francisco Franco|Franco]] forces in the [[Spanish Civil War]].<ref>{{cite web |url=http://7.62x54r.net/MosinID/MosinRareSCWM9130s.htm |title=Spanish Civil War M91/30s |website=7.62x54r.net |access-date=7 June 2011 |url-status=live |archive-url=https://web.archive.org/web/20060128160530/http://7.62x54r.net/MosinID/MosinRareSCWM9130s.htm |archive-date=28 January 2006}}</ref> Spanish Civil War Mosins can be readily identified by the wire sling hangers inserted in the slots in the forearm and buttstock meant to take the Russian "dog collars" for Russian-style slings, so the rifles could accept Western European–style rifle slings.
