The Carcano rifle, often incorrectly called the Mannlicher-Carcano or the Mauser-Parravicino, is an Italian bolt-action rifle.
The rifle was first produced in 1891, and production ended in 1945. Within that time period, over 3 million Carcano rifles were produced. Until 1938, all Carcanos were chambered in 6.5x52mm Carcano. After reports of inadequate performance of the rifle from 1924 to 1934, a newer variant was introduced, using the 7.35x51mm Carcano cartridge. In 1963, a Carcano rifle, specifically a Modello 91/38, was used by Lee Harvey Oswald to assassinate the then-United States President John F. Kennedy, to which he succeeded.
The Carcano is a bolt-action rifle with a six-round internal magazine. The rifle is not fed by stripper clips; it is instead fed by an en-bloc clip. The en-bloc clip does not pop out of the weapon when all ammunition is expended; it has to be manually pulled out from the bottom of the weapon.
Many variants of the weapon were produced, including the original Modello 91, the Modello 91/38 and the Modello 91/41 just to name a few.
