This rifle was adopted by the Russian Army in 1891, which is why its official name is M1891. Russia used the Mosin-Nagant for the first time in the Russo-Japanese War (1904-1905), and later it was also used in the First World War, the Russian Civil War and the Polish-Soviet War, among other conflicts.
In 1930 some changes were made to modernize it, which resulted in the M1891/30 variant, which would be widely used by the Red Army in World War II and also by the Republican side during the Civil War Spanish. In 1932 a sniper variant was introduced, with PE and PEM sights and an elongated, L-shaped lever. In 1942 a new sight was introduced, the PU, used among others by the famous Soviet snipers Vasily Zaitsev and Lyudmila Pavlichenko.
In 1945 the Mosin-Nagant was already obsolete, being replaced by the SKS semi-automatic carbine. However, the Mosin-Nagant continued to be manufactured in some countries and used in numerous wars.
