W+F Bern’s K31 straight-pull action is smooth and fast, and this example is chambered for the Swiss 7.5x55mm GP11 specification cartridge. The bolt components remain in the white, contrasting the blued receiver and barrel, which is characteristic of these rifles.
It is equipped with open iron sights: a drift-adjustable front post with protective ears and a tangent rear sight graduated to 1500 m. The front barrel band includes a stacking hook; the bayonet lug is a separate piece at the muzzle/front sight base, consistent with Swiss service configuration.
The hardwood stock features a full-length profile with a finger-groove fore-end and a separate top handguard. The rifle retains its right-side sling setup and has a 13.0 in length of pull, making it true to the K31 pattern.
Proofs and markings include the Swiss cross-in-shield crest on the receiver, a triangular "A" stamp on the front band, and "7.5x55 SWISS" on the barrel. A soldier’s identification tag is underneath the buttplate, aligning with Swiss military tradition and adding documented service context.
This rifle includes a detachable steel K31 magazine with a matching baseplate and an installed leather sling, rounding out a correct and complete Swiss service carbine package from 1942.
