This K31 uses the Swiss straight-pull bolt system with a top ejection port and long loading cutout, paired with a ring-style cocking piece safety. It feeds from a detachable 6-round steel box magazine for a 6+1 capacity. The matching receiver, bolt, and magazine add desirable completeness and continuity to the rifle.
The 25.6 inch barrel is outfitted with iron sights: a tangent rear sight with a V-notch slider graduated to 1500 m and a replaceable front blade in a rectangular base. The bore is bright with sharp lands and grooves, supporting the rifle’s clean internal condition.
The rifle retains a blued steel finish over its receiver and metal components. Furniture is hardwood with a full-length stock and separate top handguard. The left-side inletted sling bar, two barrel bands with forward side sling loop and stacking hook, and a steel buttplate complete the service-correct configuration. Length of pull measures approximately 12.5 inches.
Markings include the Swiss shield-with-cross crest on the receiver ring, an import mark on the barrel identifying the model and caliber, and a "P" with numerals near the sight base/receiver shank indicating post-service privatization. Made in Switzerland by Waffenfabrik Bern, this K31 reflects the distinctive design and manufacturing standards associated with its origin.
