Mosin–Nagant Model 1891/30

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 found chambered for its original 7.62×54mmR cartridge. Model 1891/30 (винтовка образца 1891/30-го года, винтовка Мосина): The most prolific version of the Mosin–Nagant. It was produced for standard issue to all Soviet infantry from 1930 to 1945. Most Dragoon rifles were also converted to the M1891/30 standard. It was commonly used as a sniper rifle in World War II. Its design was based on the Dragoon rifle with the following modifications: Flat rear sights and restamping of sights in metres, instead of arshinii. A cylindrical receiver, replacing the octagonal receiver (commonly called "hex", but actually having five octagonal top flats and a round bottom rather than three octagonal bottom flats. It has six "sides" but is neither hexagonal nor octagonal in normal use of those terms.) Early production 91/30s (from 1930 to 1936) and converted Dragoon rifles retained the octagonal receiver. These rifles are less common and regarded as generally more desirable by collectors. A hooded post front sight, replacing the blade on previous weapons.
