These k31 carbine’s are designed closely to the original Schmidt-Rubin prototype. This edition has a removable box magazine, holding five rounds but designed to be loaded with a stripper clip. The k31 was released in 1931 for the Swiss military. Straight-pull bolt action, caliber 7.5×55, and maple wood. Extremely accurate. Steel Charging knob and sling included. Excellent overall, bore is like new. This particular piece has a medallion on the stock.
