Description:

We are pleased to offer a highly desirable and collectible example of Switzerland’s iconic straight-pull service rifle: a Swiss K31 (Karabiner Modell 1931) chambered in the classic 7.5×55 Swiss cartridge. This particular rifle is distinguished by a rare and eye-catching 1931-1981 “50 Jahre Karabiner 31” commemorative medallion inset into the stock, marking the 50th anniversary of this legendary rifle’s adoption. The rifle is in excellent overall condition and comes complete with its original leather sling.

Historical Background
The K31 was adopted by the Swiss Army in 1933 as the successor to the K11, incorporating a shorter, stronger action with a massive six-lug bolt that locked at the rear. It featured a two-stage trigger that is legendary for its crispness and a refined barrel chambered for the excellent 7.5x55mm Swiss cartridge. The K31 served as the standard infantry rifle of the Swiss citizen-soldier militia for decades, and it remains one of the most respected military bolt-action rifles ever produced. The 50th anniversary medallion inset into the stock commemorates the rifle’s enduring service and the Swiss tradition of marksmanship. These commemorative pieces were produced in limited numbers and are highly sought after by collectors.

Condition and Features
This rifle is in excellent overall condition, rated 8/10, with wear consistent with age and careful use. The metal retains strong original bluing with a crisp Swiss cross crest, factory markings, and serial numbers. The bore is bright with sharp rifling, a testament to the quality of Swiss steel and proper maintenance. The action cycles with the characteristic smoothness of the K31, and the two-stage trigger breaks cleanly. The rifle passes the snap-cap test, confirming proper firing pin function.

Matching Numbers and Unmarked Magazine
The serial number 920421 is visible on both the bolt and receiver, confirming a matching bolt-receiver pairing, which is a key indicator of core integrity. The barrel shows the number 421 , which is consistent with the rifle’s serial number. This level of matching originality adds significant collector value. The magazine is unmarked, which is a notable variation. While most military-issue K31 magazines bear serial numbers to match the rifle, unmarked examples are occasionally encountered and are fully functional. This detail adds a layer of interest for collectors who appreciate production variations.

Commemorative Medallion
The standout feature of this rifle is the 1931-1981 “50 Jahre Karabiner 31” commemorative medallion inset into the stock. This medallion marks 50 years of the K31’s service and is a rare and desirable addition that elevates this rifle from a standard service example to a true collector’s piece.

Stock and Accessories
The rifle is fitted with its original walnut stock, which is solid and well-preserved with only minimal handling marks. The included leather sling is a correct period accessory that adds to the rifle’s authentic presentation. The rifle retains its correct iron sights, bayonet lug, and stacking hook.

Collector Appeal
For the collector of Swiss military arms, commemorative firearms, or those seeking a standout example of the K31, this 50th anniversary rifle offers a premier opportunity. Its excellent condition, matching numbers, rare commemorative medallion, unmarked magazine, and included sling make it a centerpiece for any collection. It is equally suitable for display, research, or as a reliable and accurate shooter. This is a tangible piece of Swiss history and a celebration of one of the finest military rifles ever produced.

Important Notice Regarding Military Surplus Firearms:

Historical Artifacts: These rifles are typically 50–100+ years old and have served through wars, training, and storage. They are collectible historical items, not new commercial firearms.
Honest Wear Expected: Minor dings, scratches, handling marks, and edge wear are normal and do not affect grading.
Wood Cracks: Hairline cracks in non-critical areas (e.g., forend, buttstock sides) are common in aged wood and do not downgrade a rifle unless they affect structural integrity. Any critical cracks will be noted.
Non-Matching Numbers: Many surplus rifles have non-matching bolts, magazines, or parts. This is common and does not necessarily affect function or value. Matching numbers will always be noted if present.
Bore Condition: Bore condition is graded separately (Excellent, Very Good, Good, Fair). A “Good” bore on a 1940s rifle is often perfectly acceptable and shootable.
Cosmoline: Rifles stored in cosmoline may require thorough cleaning before use. Cosmoline preservation is a bonus, not a guarantee of a “new” rifle.
