The TKB-408 assault rifle is an experimental Soviet assault rifle.


The TKB-408 was designed in 1946 by German Korobov, firearms designer known for designing interesting prototypes. The TKB-408 was entered into a contest to find a select-fire weapon that could fire the SKS's cartridge after the SKS was adopted, along with various other designs submitted during war trials; the TKB-408 was one of the very few bullpup designs submitted. While the TKB-408 showed promise, it ultimately lost out to the AK, and the weapon faded into history.


The weapon uses a tilting bolt system similar to older Soviet prototypes, but it is not known if this tilting bolt system is mechanically related to the one used in Sudayev's AS-44. The weapon's charging handle is located on the left side of the weapon on the gas tube and is non-reciprocating. The weapon is select-fire, and can fire in full auto or in single shots. The weapon's ejection port is located on the right side of the weapon, and has a flip-up dust cover; as the weapon's ejection port is on the right side of the weapon, it is non-ambidextrous and should not be fired by left-handers.
