Błyskawica: The Polish Home Army's Clandestine SMG
The Błyskawica was the Polish Home Army's most successful clandestine SMG, with around 750 units produced. Inspired by the Sten and MP40, it was designed for underground manufacturing in Warsaw during WWII. Its unique features include an under-folding stock, a trigger-mounted safety lever, and a dual nested recoil spring system.
