An American gas-operated semi-automatic carbine, chambered for the proprietary .30 Carbine cartridge. Despite the name, it is not the shortened variant of the M1 Garand rifle due to its own distinct design. Adopted in 1942, the M1 Carbine was the standard firearm for the US military during World War II, the Korean War and the Vietnam War. The standard feed system is 15-round magazine.
The M1A1 Carbine is the variant that features a metal side-folding stock and a pistol grip.
