The TKB-408 was an early gas-operated bullpup assault rifle with a tilting bolt. It was created by German A. 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. The firing mode selector is located on the left side of the receiver above the pistol grip. The design incorporates no provisions for firing from the left shoulder. It is chambered in the 7.62x39mm round and has an overall length of 790mm.
