Korobov and submitted to a set of official trials conducted in 1946 to select an assault rifle for the Red Army. None of the designs submitted to these trials were selected, although the AK-47 that was later adopted was a heavily modified variant of Mikhail Kalashnikov's AK-46.The TKB-408 can be fired semi- or full-automatic."@en . . . .
