The Sig AMT was the commercial version of the PE57 military rifle. They were built in 7.62 NATO and used a roller-delayed blowback system very similar to that developed by Germany during WWII and used in the StG45 and HK91 series of rifles. The AMT is built to typical Swiss standards of quality, and is an impressive rifle to handle despite its ungainly appearance.
At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
