Mosin-Nagant M1891

Origins

Russia's search for a small-bore repeater ended in 1891 with a committee compromise: the rifle of Captain Sergei Mosin of the Tula arsenal, incorporating the interrupter-equipped magazine ideas of the Belgian Léon Nagant — hence a hyphenated name Russia itself never used, calling it simply the 'three-line rifle' after the old measure of its 7.62mm bore. Its cartridge, the rimmed 7.62x54R, proved the most durable decision of all: adopted with the rifle in 1891, it remains in Russian service machine guns and sniper rifles today, the oldest military cartridge still on active issue anywhere.

Design & Construction

The Mosin action is a plain, massive turnbolt with dual front lugs, a separate bolt head, and a bolt assembly that strips without tools into large, soldier-proof pieces. Its cleverest detail answers its cartridge's worst habit: because rimmed rounds can lock rims in a box magazine, Nagant's interrupter isolates the top cartridge from the stack during feeding, and the five-round magazine loads from stripper clips through the open action. Nothing about the rifle is refined — the safety requires pulling and rotating the cock piece against the mainspring, the trigger is long, the bolt handle short and stiff — and none of it matters to function in mud or hard frost, which is what it was built for. The definitive Soviet M91/30 modernization of 1930 shortened and simplified the pattern; wartime demanded carbines (M38, M44) and above all the PU sniper variant, a selected M91/30 with a compact 3.5x scope.

Combat Use

The Mosin fought from the Russo-Japanese War onward, but its two great wars were the world wars. In the first, Russia could not build rifles fast enough and contracted Remington and Westinghouse in America to feed the front — many of those rifles ended up arming U.S. troops for training and the 1918-19 North Russia intervention when the revolution voided the contracts. In the second, the M91/30 was the basic weapon of the Red Army's infantry from the frontier disasters of 1941 to Berlin, serving beside the PPSh-41 and against the Mauser Gewehr 98's Karabiner 98k descendant. The PU sniper rifle became a Soviet institution: sniper schools trained tens of thousands, women among them — Lyudmila Pavlichenko's 309 credited kills made her the most famous — and at Stalingrad the duel of snipers became part of the battle's mythology. Finland, meanwhile, built its own excellent Mosins (the M39 among them) on captured receivers and used them against their makers in the Winter War.

Legacy

Production ended around 1948 in the USSR, but the rifle soldiered on across the socialist world — Korea, Vietnam, and beyond — and PU snipers still turn up in twenty-first-century conflicts. Enormous Cold War reserve stocks made the M91/30 the great affordable military-surplus rifle of the modern collecting era: for a generation it was the cheapest path to owning a piece of the Eastern Front, and hex-receiver Tsarist examples, American-contract rifles, Finnish rebuilds, and genuine PU snipers now form a deep collecting hierarchy. Beside the Lee-Enfield Rifle and the Mauser it completes the trinity of the great bolt-action service rifles — and it outbuilt them both.
