The K2 is an infantry rifle of the Republic of Korea Army. It is manufactured by Daewoo. It is a shoulder-fired, gas-operated, selective-fire assault rifle that feeds from a 20 or 30 round magazine and is chambered for 5.56 NATO. It uses a tough polymer for the forearm, pistol-grip and foldable buttstock. Its bolt carrier group is derived from the American M16 rifle, but the parts are not interchangeable. The complete gas operating system seems to be derived from the Galil, and consequently is more robust than the M16. The K2 uses the same magazine as the M16. The barrel rifling has 6 grooves, 1-in-7.3 right hand twist. It is a tough, durable and accurate rifle that is popular with South Korean soldiers. The K2 was available for a while in the North American firearm market with an early 90's era "thumbhole" stock, but its simple battle sights and no-frills finish never caught on with American shooters.
