K-3

The Agency for Defense Development and Daewoo Precision Industries designed the K3 between 1978 and 1987. Developed as South Korea’s third indigenous firearm following the K1 and K2 rifles, the weapon entered production in 1988. Manufacturing responsibilities transitioned through Daewoo Precision Industries, Daewoo Telecom, Daewoo Precision, S&T Daewoo, and S&T Motiv, before arriving with SNT Motiv.

The K3 is a gas-operated light machine gun utilizing a rotating bolt system, sharing visual similarities with the FN Minimi. It features a dual-feed system that accepts either disintegrating ammunition belts or box magazines. The weapon is equipped with an adjustable rear sight for windage and elevation, an adjustable front sight, and a barrel assembly with an integrated carrying handle to facilitate barrel replacement. It can be deployed on a bipod or mounted on a tripod for sustained fire. The original design did not prioritize customization, as most South Korean personnel did not require extended use of the weapon. Subsequent modernization packages introduced a side-folding adjustable stock, integral Picatinny rails on the feed cover and handguard, a carbon fiber heat shield, a modified muzzle brake, and independent bipod legs.

The firearm entered South Korean military service in 1989, replacing the M60 machine gun. South Korea retired the weapon from active service, completing its replacement with the K15 variant by late 2025. Internationally, the weapon has been adopted by Colombia, Ecuador, Guatemala, Indonesia, and the Philippines, as well as the Philippine National Police. It has seen use in conflicts including the Colombian conflict, the Gulf War, the War in Afghanistan, the Iraq War, and the Syrian Civil War. Primary variants include the experimental XK3 prototype, the standard K3, and the K3 Para, which features a shortened barrel. The platform was subsequently developed into the modernized K15 and K15 Para, which incorporate improved internal manufacturing tolerances, a push-button barrel release mechanism with positioning lugs, and integration points for day/night fire control systems.
