designer German A. Korobov in the 1960s.

A U-shaped rammer/extractor was used to chamber and extract the cartridge by pushing it into the chamber where after discharge was pulled back from the chamber and again, upon feeding the new cartridge, pushed forward and slightly up into an ejection tube above the barrel where finally exiting above the muzzle. Due to this ejection mechanism, it was possible to fire from both right and left arm positions. These weapons had the best barrel length to overall length ratio among the assault rifles.
