What’s Included
- Waffenfabrik Bern K31 rifle
- Factory Swiss steel 6-round detachable box magazine numbered to the rifle
Produced during the WWII era, this rifle falls within the 1938 serial-number range and carries the Swiss cross-in-shield crest on the receiver, underscoring its militia heritage.
The straight-pull bolt with ring-shaped charging handle allows rapid follow-up shots while retaining the robust strength expected from Swiss service arms. The detachable magazine is serial-matched, preserving the rifle’s original configuration.
A 25.67-inch barrel combined with a tangent rear sight graduated to 1500 meters and a hooded barleycorn front sight delivers the precise sight picture K31s are known for when firing standard GP11 7.5x55 mm ammunition.
The oil-finished walnut stock features a finger groove and semi-pistol wrist, offering solid ergonomics. Metal parts wear the original matte blued/parkerized finish that protected Swiss rifles in alpine conditions.
With only about 528,000 K31s produced between 1933 and 1958, examples from the pre-war years remain highly desirable, particularly those retaining strong mechanical condition and matching components like this one.
