S&T K2C1 (v.1034)

Daewoo Precision Industries K2 assault rifle is the service rifle of the South Korean military. It was developed by the South Korean Agency for Defense Development and manufactured by SNT Motiv (formerly Daewoo Precision Industries) and Dasan Machineries (since 2016). Shoulder-fired and gas-operated, the K2 is capable of firing both 5. 56×45mm NATO and . 223 Remington ammunition S&T Motiv developed the K2A to enhance its domestic appeal, which retained the full-length K2's features (including bayonet lug) and utilized the upgrades of K2C, such as the Picatinny rail on the upper receiver and handguard, as well as an Colt M4-style collapsible stock. It is slightly heavier than the original model, partly due to the screw attachment method of its rail, weighing 3. 6 kg (7. 9 lb), while the original K2 weighed 3. 4 kg (7. 5 lb). Afterward, the K2A was renamed to K2C1. The "C" in the name represented that only the exterior design was modified, without any enhancements made to its performance, in accordance with the Korean Defense Specifications (KDS). Subsequently, the K2C1 was selected by the ROK forces as their standard weapon. The K2C1 underwent various changes compared to the K2A, which included an extended handguard rail with optional lower and side Picatinny rail sections, a flattop upper receiver featuring a detachable rear backup sight, and a new Magpul CTR-like collapsible stock. As of 2016, approximately 200,000 K2C1s were in active service with frontline troops.
