S/N: 869XXX .308/7.62×51 NATO K31


K31: The Swiss Karabiner Model 1931 better known as the K31 was the replacement for both the model 1911 as well as the K11. It was the standard-issue service rifle for the Swiss armed forces from 1933 until 1958 where it was later replaced by the STG-57. This makes the K31 the last bolt action service rifle for the Swiss, however, particular cases and modified versions remained in service well into the 1970’s likely for its reliable action and accurate performance. The K31 features a 25.67” barrel and is chambered in the 7.5x55mm Swiss (GP11) and utilizes a 6 round detachable magazine. Interestingly, the K31 is indeed a straight-pull carbine based upon the many Schmidt-Rubin service rifles, however, the K31 was not designed by Rudolf Schmidt because he had passed away by then. It is undeniable his influence is seen throughout the rifle. Colonel Furrer designed the K31 at Waffenfabrik Bern. Since the Swiss had remained neutral throughout the entire Second World War; these rifles are all in much greater condition than the other European service rifles. Only 528,230 K31’s were produced from 1931-1970 and each batch has unique differences reflecting on the decisions made by the Swiss military.

Condition: The K31 pictured is the item for sale. This K31 is in very good condition. This K31 is a .308/7.62×51 version. These rifles were often made for NATO embassies by the Swiss. The chamber is made for the .308 Winchester cartridge so you can safely fire both .308 and 7.62 NATO out of this K31 carbine. The stock is in good condition but has some pressure marks along the handguard and the rear stock. There are some tiger stripes on the buttstock. The bluing is full and strong throughout the rifle with only minimal wear. All serial numbers are matching (Includes original issue sling and muzzle cap.) Very good barrel with strong lands and grooves and a nice bright bore. There may be some old oil inside so clean the barrel out with oil and a nylon brush! The bolt and bolt face look excellent, and the action still feels strong and buttery smooth. This is a collectors must have as .308 K31s are VERY rare. According to this rifle’s serial number it was manufactured by Waffenfabrik Bern in 1946.
