Primer 208: Swiss Karabiner 31

The WF-51 was a Swiss intermediate-cartridge rifle developed by Adolf Furrer at Waffenfabrik Bern, inspired by the German FG-42. It featured a unique tipping bolt mechanism and was chambered in 7.5x38mm, with 35 units produced for trials. Although it did not enter service, its development influenced later Swiss firearms before the adoption of the SIG Stgw 57.

This review delves into the Swiss K31, highlighting its historical development as a shorter, more accurate rifle than its predecessors. It clarifies common misconceptions about its design lineage and details significant mechanical upgrades like a shortened bolt and forward-locking lugs. The video demonstrates the unique straight-pull action, detachable magazine, and provides a thorough guide to field stripping and reassembly, concluding with impressive accuracy potential.

The Stamm-Saurer Model 1907 was a rare Swiss straight-pull bolt-action rifle developed by Hans Stamm for Saurer to compete for military contracts. Despite its high quality and innovative features like a unique rear sight and integrated cleaning rod, it was rejected by the Swiss military. The rifle competed against the Schmidt-Rubin K11 and G11, ultimately losing due to existing institutional knowledge of the Schmidt-Rubin and Saurer's refusal to license production.

The Stamm-Zeller 1902 was an early attempt at a semi-automatic rifle developed by Hans Stamm and Zeller & Cie, converting a straight-pull action to gas operation. Despite high-quality Swiss manufacturing and innovative features like a unique safety/re-cocking lever, it was rejected by military trials. Only a handful of prototypes were produced, making it a rare piece of early semi-automatic firearm development.
