1947 Swiss K31 Straight-Pull Carbine in 7.5x55mm - Waffenfabrik Bern
Made in 1947 by Eidgenössische Waffenfabrik Bern, this Karabiner Modell 1931 (K31) is a Swiss straight-pull bolt-action rifle chambered for the 7.5x55mm GP11 cartridge. Known for precise machining and forward-locking lugs, the K31 earned a reputation for excellent accuracy and smooth operation. Matching serial numbers on the receiver and bolt confirm the rifle’s original pairing, and the Swiss cross-in-shield crest remains clear on the receiver ring.

What’s Included
- Swiss Waffenfabrik Bern K31 bolt-action rifle (magazine not included)
The straight-pull action allows the shooter to cycle the bolt by pulling straight back and pushing forward, keeping the rifle on target and enabling rapid follow-up shots. Swiss engineers lapped the bolt lugs at the factory, contributing to the smooth feel and consistent lock-up that collectors value.
A 25.7-inch barrel and tangent rear sight graduated from 100 to 1500 meters demonstrate the rifle’s original role as a precision infantry carbine for the Swiss Army. The hoodless knife-blade front sight is protected by twin ears, while the side-mounted sling positions support field carry.
The oil-finished hardwood stock features a finger-groove fore-end, pistol-grip wrist, and a buttplate with a storage trap. A front stacking rod remains in place, underscoring the rifle’s complete military configuration.
C.A.I. Georgia VT import markings are stamped on the receiver, documenting its lawful importation into the United States. Approximately 528,000 K31 rifles were produced from 1933 to 1958, and examples from the immediate post-war years like this 1947-dated carbine remain sought after for their craftsmanship and match-grade accuracy with GP11 ammunition.
