The Mosin–Nagant is a five-shot, bolt-action, internal magazine–fed military rifle. Known officially as the 3-line rifle M1891, in Russia and the former Soviet Union as Mosin's rifle (Russian: винтовка Мосина, ISO 9: vintovka Mosina) and informally just mosinka (Russian: мосинка), it is primarily chambered for the 7.62×54mmRcartridge.

It is one of the most mass-produced military bolt-action rifles in history, with over 37 million units produced since 1891. Despite its age, it has been used in various conflicts around the world to the present day.
