M-1 is a type of military rifle that was widely used by the United States during World War II and the Korean War. It is a semi-automatic weapon, meaning it fires one round with each pull of the trigger, and it was known for its accuracy and reliability. The M-1 was chambered for the .30-06 Springfield cartridge, which provided significant stopping power. The design of the M-1 was innovative for its time, featuring a gas-operated mechanism that allowed for faster firing compared to bolt-action rifles. It was replaced by the M14 rifle in the late 1950s, but the M-1 remains a significant part of military history and is still popular among collectors and shooting enthusiasts today.
