South Korean Special Forces(ROKSF) will be purchasing some piston-driven AR manufactured by Dasan Machineries. Dasan Machineries was chosen as the preferred suppliers to replace its aging Daewoo K1A carbine.
Some interesting tidbits
piston system(possibly short stroke)
uses two stage trigger. Trigger pull weight is reportedly around 4.5 lbs
no forward assist
quad rail system, possibly with QD mount
ambidextrous safety, magazine release
selector can be put on safe even with hammer down
About 1,000 will be supplied in a few months, followed by more purchases(around 10,000 units) later.
The red dot sight is from a company called EO Systems.
S&T Motiv(formerly Known as Daewoo) is the company in charge of South Korea's standard issue rifles. Recently some information came out regarding a new rifle that looks like an AR variant.
Looking at the video, it seems to have ambidextrous features for safety selector, magazine release, and bolt release. It's unclear how the new bolt release systems works as a bolt lock or not, but unlike a lot of AR, it is located right in front of the trigger guard.
Gas systems seems to be a short-stroke gas system.
Some parts are reusing K1 and K2 rifles parts, such as magazine release and selector lever.

SK SOF runs the HK416, but as everyone in the world knows, H&K Customer Service is famously German LMAO... hence the need for this SK domestic clone pic.twitter.com/W4GTJT0Cr0
Supposedly it uses 1:7 twist barrel in 12 to 16 inches
Instead of updating the K1/K2 like with K2C1 and K2C , it's a possible change from nearly 40 years of K1/K2 design. It's unknown what prompted this change, but it will be interesting how this develops from here.
LAV shoots the Egyptian licensed version in this video, which is essentially the same.
This gun was well-regarded and had uses outside of US Special Forces during the Vietnam War as some helicopter pilots carried it. There was a story called 'The Curse of Swedish K' from a long time ago.
The gun also made an appearance in movie 'Godfather'
This was another attempt at making cheaply made firearm for resistance in enemy territory, just like the Liberator pistols. The difference was that this was in 9mm(Liberator was .45 ACP) and is made of cast steal(Liberator was stamped steal)
