The M1 carbine is a lightweight, easy to use semi-automatic carbine that became a standard %uFB01rearm for the U.S. military during World War II, the Korean War and the Vietnam War, and was produced in several variants. It was widely used by U.S. and foreign military, paramilitary and police forces, and has also been a popular civilian %uFB01rearm. A total of over 6.5 million M1 carbines of various models were manufactured, making it the most produced small arm for the American military during World War II. Despite being designed by Winchester, the great majority of these were made by other companies : the largest producer was the Inland division of General Motors, but many others were made by contractors as diverse as IBM, the Underwood Typewriter Company, and the Rock-Ola jukebox company. The Chiappa Firearms’ M1 series is a fine replica of the M1 carbine, featuring a blowback system and an adjustable rear sight, which can be removed to leave guides free for optics mount. The barrel and bolt are made of solid steel, the trigger guard and magazine of polymer. A wooden stock version and a black synthetic stock version are available. By the M1.22LR caliber the stock is interchangeable with the original. Components are CNC machined and are interchangeable with original M1 parts.
