1962 model

guns.ru just posted an article on the Korobov TKB-022, an early bullpup assault rifle designed by Russian gun designer G. A. Korobov.

All weapons were tested by Soviet army, but turned down on unpublished reasons (most probably becuse the gun was simple too advanced for contemporary military thinking, but also possibly because no-one at the time could tell for sure if plastic housing would hold its integrity in extreme weather conditions or during many years of storage or use).
