Despite being able to produce their own service rifle, it was not an ideal arrangement; the original license agreement did not cover enough weapons to equip their forces including millions of reserves, and having to pay license fees to manufacture the design was too expensive at a time when the country was short on foreign currency. Geopolitical considerations played a factor, as the Nixon Doctrine and Carter administration's use of the U.S. military presence on the Korean peninsula as leverage to force change against South Korea's human rights practices. Under such influences, South Korea felt it necessary to be able to control their own basic weapon needs. Facing the eventual expiration of the Republic of Korea's license to produce the M16A1 (Colt Model 603K), president Park Chung-hee, who strongly believed in self-reliance in national defense, ordered the development of an indigenous standard military firearm.
