Mosin Nagant M91/30

The M91/30 is 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. Early sniper versions had a 3.87×30 PE or PEM scope, a Soviet-made copy of a Zeiss design, while later rifles used smaller, simpler, and easier-to-produce 3.5×21 PU scopes. Because the scope was mounted above the chamber, the bolt handle was replaced with a longer handled, bent version on sniper rifles (known to Mosin collectors and shooters as a "bent bolt") so the shooter could work the bolt without the scope interfering with it. Like the US M1903A4 Springfield sniper rifle, the location of the scope above the receiver prevents the use of stripper clips.
