Is the K98K Mauser One of the World's Greatest Battle Rifles?

The major rifle faced by the Allies in World War II was Germany’s Mauser K98k that was issued to all branches of its military. Since 1898, the gun’s rugged strength and reliability was as feared on the battlefield as it was celebrated in the hunting fields, and to this day Mauser’s action remains a top choice for a custom rifle. Between 1934 and 1945, more than 14 million 7.92x57 carbines were produced among the Axis factories throughout the Third Reich.

The original concept underwent considerable change during World War I. Germany’s Mauser Gew 98, with its 29.1-inch barrel and straight bolt handle, was designed for an open battlefield against line formations and cavalry similar to those faced in Napoleonic times.

In 1914, all that fell apart in the face of machine guns and high explosive artillery. The long Gew 98 proved equally unwieldy in the trenches and within cities. Sighted for a point-blank zero of 400 meters meant aiming very low when firing at the closer-range opponents in trenches or behind walls. As reality set in, the shortened K98a carbine appeared, although wartime needs meant rifles and carbines were turned out together rather than making a production switch midstream.

The Gew 98’s cartridge was a game-changer worldwide. The 7.92x57—also known as the 8x57—was topped with a new flat-shooting ballistically superior 154-grain flatbase spitzer pointed bullet at 2,880 fps rather than the heavy roundnose bullet at 2,000 to 2,300 fps then in general use worldwide.

Conceptual Birth

The Gew 98 and 7.92 quickly became the models for the U.S. M1903 and our new .30-06 round. It was copied so closely that Mauser won a judgment for patent infringement against the U.S. in American courts.

Postwar, the Treaty of Versailles stripped Germany of any but token military ability. The newly formed state of Czechoslovakia found itself in need of small arms. Mauser, with excess capacity, sold a complete Gew 98 rifle manufacturing plant to the Czechs, and their first product was the 24-inch-barreled M1924 rifle that quickly became a hit worldwide. FN in Belgium had been making Gew 98 rifles during World War I and followed with its own 24-inch M1924, and soon the Czechs and Belgians were in competition, rearming militaries worldwide.

Mauser Waffenfabriken changed its name to the less warlike Mauser Werke Oberndorf AG and secretly began work on a rifle called the Standard Modell. By 1933, Hitler was in charge, and the Standard Modell was issued to the German Post Office. It was now very close to the K98k of World War II.

Minor changes improved the Standard Modell, and it became the Karabiner 98 kurz. Overall length was 43.7 inches, with a barrel of 23.62 inches, and a tare weight of 8.38 pounds.

Function and Use

The five-shot magazine could be loaded singly or via a five-round charger, and a soldier could fire eight to 10 shots per minute. The four-groove barrel had a right-hand twist of 1:9.45. The front sight was an inverted V, allowing a little latitude for windage adjustment. The rear sight with its V notch was now graduated from 100 meters to a rather optimistic 2,000 meters but without windage.

During World War I, the original 154-grain load performed well in the Gew 98, but it didn’t provide sufficient long-range power in machine guns, and a new 196-grain load featuring a spitzer boattail was issued for those. During K98k, development, the 154-grainer created excessive muzzle blast, and Germany settled on the 196-grain load for all its small arms.

The K98k is simple to use. Open the bolt, draw it all the way back and the magazine follower pops up, holding the bolt open. Insert the charger and press straight down. A scallop on the left side of the receiver ensures the thumb easily presses the five rounds flush into the magazine. The rounds orient themselves for feeding from either side of the magazine.

In closing the bolt, the extractor picks up the cartridge rim as it rises from the magazine in controlled-round feed, meaning if anything goes wrong in the loading cycle, such as a defective round, a quick backward jerk of the bolt will eject the cartridge. That feature is what makes the Mauser-system rifles so popular with hunters of dangerous game.

Swing Safety

With the bolt closed, swing the wing safety over 90 degrees from left to right. The rifle is now on Safe, and the bolt locked closed. To fire, swing the safety with your right thumb 90 degrees from right to left.

World War II saw major changes. The beautiful bluing and oil-finished walnut stock with many of the elegantly machined parts carefully numbered to the gun slowly gave way to stampings for the trigger guards and spot-welded barrel bands, laminated wood stocks, far less polish, and Parkerizing instead of bluing.

The once-prolific serial numbering of the parts was reduced to speed production. Late war guns may have a mix of machined and stamped parts as older stocks were depleted. My example with code “dot” atop the receiver was made by Waffen Werke Brünn, the German name for the city of Brno in Czechoslovakia. It’s dated 1944. Only the barrel and stock have a serial number.

This one might very well be a Russian capture, but has anomalous features. The Russians captured millions of rifles and rebuilt them postwar. They struck the top of the receiver with an X, took them apart, reblued them and reassembled them without the cleaning rod, sight hood and the lock screws on the trigger guard screws. They electro-penciled the receiver’s serial number on the mixed parts of the bolt, floorplate, trigger guard and others. The extractor turned red after rebluing.

Russian Captures?

I purchased this rifle at an estate sale, and the various machined, stamped and missing parts are the hallmarks of a Russian capture. However, it does not have the electro-penciling, and it’s missing the X and an importer’s mark, so its postwar history will remain a mystery. I’ve since added lock screws and the 12.5-inch cleaning rod segment and replaced the broken red extractor with a new one.

Many K98ks are found with mismatched bolts, since the Allies separated the rifles from their bolts when surrendered. If you end up with one of these, have the headspace checked before shooting it.

Prices are currently sky-high for rifles with matching serial numbers, fetching $2,500 to $4,000 depending on condition. Russian capture and mismatched guns can be quite reasonable, selling for just above or below $1,000.

Back in the early 2000s, Mitchell’s Mausers rebuilt quite a few World War II K98k rifles in Yugoslavia and force-matched the serial numbers. As a rule, they are good-looking shooters and hover in price around the Russian captures and wartime bring-back.

Collector's Items

The plethora of gadgetry issued to the German soldier is equally fun to collect. The unique sling is complicated and expensive, but it’s easy to adjust, and the cleaning kit is full of seemingly incomprehensible tools. Many of the uniforms and leather gear are faithfully replicated.

Today’s collector’s pieces require deep pockets. Tread carefully, and buy only from reputable dealers. Although now out of print, Backbone of the Wehrmacht, The German K98k Rifle, 1934-1945 by Richard D. Law is a very detailed reference on their construction and seemingly endless markings. The book can be found on eBay and other sites.
