SIG PE-57: Swiss Roller-Delay (the Civilian Stgw 57 aka SIG 510)
This video provides an in-depth look at the SIG PE-57, the civilian semi-automatic variant of the Swiss Stgw 57 service rifle. It delves into the rifle's design lineage, tracing influences from the German MG-42 and FG-42. The analysis highlights the roller-delayed blowback action, the 7.5x55mm Swiss cartridge, and its unique in-line stock layout designed to minimize muzzle climb. The video also touches upon its variants like the SIG AMT, its use by foreign militaries, and practical aspects such as the bipod and magazine capacity, ultimately concluding that despite its unusual appearance and weight, it handles well and excels at long-range precision.
