Originally, the Karabiner 98k iron sight line had an open-pointed-post-type (barlycorn) front sight, and a tangent-type rear sight with a V-shaped rear notch. The Karabiner 98k rear tangent sight was flatter compared to and does not obstruct the view to the sides during aiming as the Langevisier. The impractical Langevisier or 'rollercoaster' rear sight of the Mauser Gewehr 1898 was replaced with a conventional tangent leaf sight. From 1944 onwards phosphating/ Parkerizing was introduced as a more effective metal surface treatment. Such a thin black oxide layer provides only minimal protection against rust or corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic corrosion. The metal parts of the rifle were blued, a process in which steel is partially protected against rust by a layer of magnetite (Fe 3O 4). The joined rods from 3 rifles provided one full-length cleaning rod. Each rifle was furnished with a short length of cleaning rod, fitted through the bayonet stud. 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. The straight bolt handle found on the Gewehr 98 bolt was replaced by a turned-down bolt handle on the Karabiner 98k. After loading, the empty clip is ejected when the bolt is closed. Its internal magazine can be loaded with five 7.92Г—57mm Mauser cartridges from a stripper clip or one-by-one. The Karabiner 98k is a controlled-feed bolt-action rifle based on the Mauser M98 system. Patrone became the standard German service ball cartridge in the 1930s. Because of this the S Patrone was phased out in 1933 and the s.S. Patrone, originally designed for long range machine gun use, produced less muzzle flash out of rifles that had a shorter barrel and also provided better accuracy. The 1903 pattern 7.92Г—57mm Mauser S Patrone produced excessive muzzle flash when fired from arms that did not have a long barrel like the Gewehr 98.

The desire for adopting new shorter barreled rifles and the introduction of the Karabiner 98k, featuring a 600В mm (23.62В in) long barrel, were reasons for changing the standard German service ball rifle cartridge. Just like its predecessor, the rifle was noted for its reliability, safety and an effective range of up to 500 metres (550В yd) with iron sights and 1,000 metres (1,090В yd) with an 8Г— telescopic sight. Since the Karabiner 98k rifle was shorter than the earlier Karabiner 98b (the 98b was a carbine in name only, as it was in reality a version of the Gewehr 98 long rifle designated a carbine to adhere to the Treaty of Versailles the 98b was additionally fitted with a tangent rear sight rather than the more claustrophobic 'Lange' ramp sight), the new rifle was given the designation Karabiner 98 kurz, meaning 'Carbine 98 Short'. The Karabiner 98k was derived from earlier rifles, namely the Mauser Standardmodell of 1924 and the Karabiner 98b, which in turn had both been developed from the Gewehr 98. In February 1934 the Heereswaffenamt (Army Weapons Agency) ordered the adoption of a new military rifle.

Millions were captured by the Soviets at the conclusion of World War II and were widely distributed as military aid. It was one of the final developments in the long line of Mauser military rifles.ДЄlthough supplemented by semi-automatic and fully automatic rifles during World War II, the Karabiner 98k remained the primary German service rifle until the end of the war in 1945. It was adopted on 21 June 1935 as the standard service rifle by the German Wehrmacht. The Karabiner 98 kurz ( German: ' carbine 98 short'), often abbreviated Karabiner 98k, Kar98k or K98k and also incorrectly sometimes referred to as a K98 (a K98 is a Polish carbine and copy of the Kar98a), is a bolt-action rifle chambered for the 7.92Г—57mm Mauser cartridge.
