1927 Radom Polish K98 Mauser Sporterized - Penny Auction - NO RESERVE!

A Highly Collectible Polish Polish Contract Action Repurposed for Sport

The Polish K98 (Karabinek wz. 98) is a historically significant military bolt-action rifle produced at the Pa?stwowa Fabryka Karabinów (State Rifle Factory) in Radom, Poland, during the interwar period. Closely patterned after the German Karabiner 98a, these Polish Mausers are highly sought after by military surplus enthusiasts due to their exceptional manufacturing quality, smooth actions, and limited production run before the outbreak of World War II.

This specific receiver, carrying serial number 4057, was manufactured in 1927 and is chambered in the powerful 8mm Mauser (8x57mm JS) cartridge. During the mid-20th century, many of these surplus rifles were imported and customized by American marksmen to create optimized hunting and target rifles. This specimen is a classic representation of that era’s craftsmanship, having been customized into a dedicated target configuration featuring highly precise, vintage aftermarket sights.

Condition and Action Highlights

Overall Status: Presented as a classic vintage sporterized project rifle. While the military configuration has been altered, the barreled action remains in excellent mechanical condition and is fully functional.

Sporterized Stock Configuration: The original military stock has been modified to a lighter, sporterized profile to shed weight and accommodate aftermarket sights. The wood is structurally sound without cracks, showing standard field dings, handling marks, and finish thinning consistent with age and active field use. (Please refer to the listing pictures for exact stock modification details and cuts).

Aftermarket Target Sights: The rifle has been upgraded with a vintage Armstrong target receiver sight mounted to the rear. To align with this precision aperture, a modified aftermarket front sight post has been securely added to the muzzle end of the 24-inch barrel.

Receiver Modifications: The receiver bridge has been drilled and tapped to facilitate the installation of modern scope mounts or target sight bases.

Metalwork and Barrel Finish: The metal surfaces retain a fair to good amount of their blued finish, showing typical age-related wear, thinning, and high-edge silvering, but remaining free of active rust or deep pitting.

Mechanical Operations and Bore: Mechanically excellent. The classic Mauser 98 bolt cycles with signature smoothness, locking up tightly into battery. The trigger pull is crisp, and the internal safety functions as intended. The bore remains in surprisingly good condition, with strong, distinct rifling.
