Here is my ZKK 601 in .308. Bought it well used years ago. It is the older type from 1977 with the cute fold-down peepsight in the receiver bridge. It came with the ugly "de luxe" stock with square foreend, white-line spacers and a perished ventilated recoil pad. Shortened the barrel to 20", reshaped the stock, put a steel gripcap, horn foreend tip, ring swivel base and oil finish on.
