The Izhmash Los (Russian: "Лось" meaning "moose") was a hunting and sporting rifle originating in the Soviet Union (USSR). It was designed by A.S. Shesterikov and was in limited production from 1961, and went into mass production around 1965. It was first produced by Izhmash, which became Kalashnikov Concern, who discontinued the rifle in 2017(?).
Throughout many years of production, it was offered in many chamberings including 9x53mm, 9.3x64mm, 7.62x51mm A Soft Point (proprietary cartridge not compatible with 7.62 NATO or .308 Winchester...?), .308 Winchester, .30-06 Springfield and 7x65mm.
Its smaller-caliber counterpart was the Izhmash BARS, which came chambered in 5.6x39mm (aka .220 Russian), 7.62x39mm and .223 Remington. Along with the Los, the Bars was discontinued and replaced with the Baikal 145 Los.
