Historical profile

Developed by the ADD in the late 1970s to replace the Colt-licensed M16A1; entered service in 1984 as the standard rifle of the ROK Army.

Combines AR-15 features (modularity, ergonomics) with Eugene Stoner's AR-18 short-stroke gas piston system, more tolerant of fouling.

Exported to several countries (Nigeria, Philippines, Peru, Bangladesh) and produced under license in Nigeria as the OBJ-006.
