This is the Daewoo Max II rifle. This is one of the best rifles out there in my opinion. This was adopted around 1982 by the South Korean Armed Forces. I have shot them while there training with the ROK Marines. It has all the best features of the AR15/M16, AK47 and the FN-FAL. I will do a far more detailed review of this rifle with accuracy tests.. This rifle is piston driven...and was so before it was cool. This was an informal video and the wind over powered the camera microphone.
