This CZ Model S rifle is one of many prototypes made between the world wars in Czechoslovakia in an effort to develop a military semiautomatic rifle. Similar efforts were underway in most other countries at the same time (basically every place that had a mature arms industry), and a huge variety of ideas were tried out.
In this case, we have a gas operated, tilting bolt rifle design. It is chambered for the 8×57 Mauser cartridge, and uses a 10-round detachable magazine. This rifle has a 1929 acceptance mark, which dates it nicely for us. It was designed by a team including one of the Holek brothers, and did better than its competition in trials – but not well enough to be accepted by the Czech military or to attract any outside commercial interest. Holek would go on to design the ZH-29 rifle, and CZ would move on to a series of other designs that ultimately led to naught.

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!
