The Spz-kr was an assault rifle that was invented during the latter days of the Third Reich. It was one of the "last-ditch" weapons alongside the VG 1-5, StG 45(M), and MP 3008.
The overall weapon is largely made up from Sten MKII submachine gun components, most notably the receiver and buttstock. The magazine and magazine release are from the StG-44. All variants are capable of semi-automatic and sustained fire. Single-shot fire could be applied by pulling the trigger half way, while pulling the trigger further to the rear produced burst fire. This function predates the similar operation used on the present day Steyr AUG series of rifles. It was designed by Heinrich von Wimmersperg of Austria, who after WWII, moved to Detroit, Michigan, as part of Operation Paperclip, and continued to invent and design. In his later years, he designed many car seats for infants and toddlers.
