Karbiner98K / KAR98K

Karbiner98k

The Karabiner 98 Kurz (often abbreviated Kar98k, K98, or K98k) was a bolt action rifle chambered for the 7.92×57mm Mauser cartridge that was adopted as the standard service rifle in 1935 by the German Wehrmacht.[2] It was one of the final developments in the long line ofMauser military rifles. Although supplemented by semi- and fully automatic rifles during World War II, it remained the primary German service rifle until the end of World War II in 1945.



History


The Karabiner 98k was derived from earlier rifles, namely the Mauser Standardmodell and the Karabiner 98b, which in turn had both been developed from the Gewehr 98. Since the Karabiner 98k rifle was shorter than the earlier Karabiner 98b (the 98b was a carbine in name only, a version of Gewehr 98 long rifle with upgraded sights), it was given the designation Karabiner 98 Kurz, meaning "Carbine 98 Short". Just like its predecessor, the rifle was noted for its reliability, great accuracy and an effective range of up to 500 metres (550 yd) with iron sights and 1,000 metres (1,090 yd) with an 8× telescopic sight.

Design details


Features




The Karabiner 98k was a controlled-feed bolt-action rifle based on the Mauser M 98 system. It could be loaded with five rounds of 7.92×57mm Mauser ammunition from a stripper clip, loaded into an internal magazine. Alternately, cartridges could be loaded singly into the magazine by hand. The straight bolt handle found on the Gewehr 98 bolt was replaced by a turned-down bolt handle on the Karabiner 98k. This change made it easier to rapidly operate the bolt, reduced the amount the handle projected beyond the receiver, and enabled mounting of aiming optics directly above the receiver on the Karabiner 98k. Each rifle was furnished with a short length of cleaning rod, fitted through the bayonet stud. The joined rods from 3 rifles provided one full-length cleaning rod.

The metal parts of the rifle were blued, a process in which steel is partially protected against rust by a layer of magnetite (Fe3O4). Such a thin black oxide layer provides minimal protection against rust or corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic corrosion. From 1944 onwards phosphating/Parkerizing was introduced as a more effective metal surface treatment.

Sights

Originally the Karabiner 98k iron sight line had an open post type front sight, and a tangent-type rear sight with a V-shaped rear notch. From 1939 onwards the post front sight was hooded to reduce glare under unfavourable light conditions and add protection for the post. These standard sight lines consisted of somewhat coarse aiming elements making it suitable for rough field handling, aiming at distant area fire targets and low light usage, but less suitable for precise aiming at distant or small point targets. The rear tangent sight was graduated for 1935 pattern 7.92×57mm IS cartridges from 100 m to 2000 m in 100 m increments. These cartridges were loaded with 12.8 g (197 gr) sS (schweres Spitzgeschoß – "heavy pointed bullet") ball bullets.


Stock


Early Karabiner 98k rifles had walnut wood one-piece stocks. From 1938 onwards the rifles had laminated stocks, the result of trials that had stretched through the 1930s.[5] Plywood laminates are stronger and resisted warping better than the conventional one-piece patterns, did not require lengthy maturing, and were cheaper. The laminated stocks were due to their dense composite structure somewhat heavier compared to one-piece stocks.In addition to the use of Walnut and Beech laminate, Elm was used in small quantities. The butts of the semi-pistol grip Karabiner 98k stocks were not uniform. Until early 1940 the stocks had a flat buttplate. After 1940 some stocks had a cupped buttplate. Some stocks had a metal buttplate.




Accessories


When issued the Karabiner 98k came accompanied with assorted accessory items including a sling, a protective muzzle cover, and for field maintenance a Reinigungsgerät 34 (Cleaning Kit 34) or RG34 kit. Introduced in 1934 the Reinigungsgerät 34 consisted of a flat 85 mm (3.3 in) wide by 135 mm (5.3 in) long sheet metal container with 2 hinged lids carried on the person which held an oiler, a take down tool for removing the floorplate and cleaning the receiver of the rifle, an aluminum barrel pull-through chain, a cleaning and an oiling brush, and short lengths of tow used as cleaning patches.

The Karabiner 98k rifle was designed to be used with an S84/98 III bayonet.The S84/98 III had a blade length of 252 mm (9.9 in) and an overall length of 385 mm (15.2 in) and was accompanied by a bayonet frog.Older bayonet types designed for the Gewehr 98 could also be mounted and were used during World War II as well.Other accessories to fire rifle grenades or reduce the sound signature during firing were designed for the Karabiner 98k.
