The Dasan Machineries DSAR-15 is a 5.56×45mm NATO selective fire AR-15–style assault rifle manufactured by Dasan Machineries.

To replace the outdated K1A in service, the Republic of Korea Armed Forces initiated two submachine gun acquisition programs:^[2]

1. Special Operations Submachine Gun Type-I, first announced in 2016, which focuses on developing new weapon systems intended for large-scale deployment to across all branches of Republic of Korea Armed Forces.
2. Special Operations Submachine Gun Type-II, first announced in 2019, which focuses on acquiring already-developed weapons in smaller quantities to meet immediate operational demand, primarily from Republic of Korea Army Special Warfare Command.

For the Type-I program (provisionally named K16 at the time by the media, though this designation was later officially assigned to the S&T Motiv K16 general-purpose machine gun chambered in 7.62×51mm NATO), there would be three years of development and one year of feasibility study between 2020 and 2024, with mass production scheduled to commence by 2024.^[3]

On 23 June 2020, the DSAR-15PC—a variant of the DSAR-15 modified with a short-stroke gas piston operating system and designed for close-quarters battle—was chosen as the base model for the Type-I program. This decision followed a competition against the S&T Motiv STC-16.^[4] According to an unnamed South Korean military official, special forces personnel from the 707th Special Mission Group and the 13th Special Mission Brigade were to receive 1,000 DSAR-15PCs. 15,000 DSAR-15PCs with modifications based on feedback would be delivered by 2023.^[5]

However, the DSAR-15PC was canceled in June 2021 due to allegations that a former executive of the manufacturer had leaked military secrets. This setback forced the program to start over and select alternative firearms.^[6][7] There are allegations that the cancellation was politically motivated.^[8]

The Type-I program eventually restarted in 2023. Despite facing penalties, Dasan Machineries, initially a preferred bidder, is expected to bid for the program with the new DSAR-15PQ model, which feature a quick-release barrel.^[2]

Meanwhile, in the Type-II program, the S&T Motiv STC-16 was selected and designated as K13 in October 2023. An initial batch of 1,710 was ordered, while an improved version will be offered to compete against the Dasan DSAR-15 offering for the reinitiated Type-I project to deliver another 16,000 carbines.^[9][10]
