Blyskawica submachine gun was designed and produced by the Polish resistance during the WW II. It was technologically related to the British Sten. A limited number was made between 1943-44.

 
Blyskawica was blowback operated. It fired from open bolt and was fed from a 32 round box magazine (interchangeable with Sten magazines). Blyskawica could only be fired in full auto. Sights had two setting: 100 and 200 meters. Despite being made by underground armories it was very well made and finished.

 
Blyskawica was used by the Polish resistance.
