DSAR15PC was selected on June 23, 2020 to replace K1A submachine gun in service in the Republic of Korea Army Special Warfare Command after competing against S&T Motiv STC-16. The Republic of Korea Armed Forces classifies K16 as submachine gun for same reason as K1A while its general characteristic is closer to assault rifle or carbine. K16 will undergo 3 years of development and 1 year of feasibility study in between 2020 and 2024, and start mass-producing by 2024. However, in June 2021, the DSAR-15PC was cancelled as the base model for the special operational submachine gun development project due to allegations of leaking military secrets by a former manufacturer's executive. As a result, the project returned to square one, forcing the selection of other firearms.
