The Czech Samopal vz. 26 was one of a family of submachine guns (the vz 23-26) that pioneered the use of bolts telescoped out forward over the barrel, allowing guns to have much better ratios of barrel to receiver length than before. The guns actually have quite a few interesting mechanical details, although in my opinion they fail to make it a particularly desirable gun for actual shooting.
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!
