Gewehr98
The Gewehr 98 (abbreviated as Gew 98 or G 98 ), is a German bolt-action rifle that was adopted in 1898. The G 98 was developed to replace the earlier G 88 rifle.
Kar98A
The Kar98a carbine made in 1918 and used in World War One, and then refurbished by the Weimar government and used by police forces. It probably remained in police use through World War Two, eventually brought to the US as a souvenir of an American soldier.
Kar98B
The Karabiner 98b (abbreviated Kar 98b or K 98b ), is a German bolt-action rifle adopted in 1923. It is an upgraded version of the Gewehr 98. Unlike other rifles named ‘Karabiner’, this weapon was not designed as a carbine, the name is simply a way to get around the Treaty of Versailles, which only allowed Germany to produce carbine rifles.
Kar98AZ
The “Kar98az” is a German World War I-era carbine rifle, later officially designated the Karabiner 98a or Kar 98a. It is a shortened version of the full-sized Gewehr 98 rifle, designed to be a more compact and handier weapon for troops like cavalry, artillery, and stormtroopers. After the war, it was considered the best rifle Germany was allowed to keep under the Treaty of Versailles and was succeeded by the similar but even shorter Karabiner 98k in 1935.
Gewehr98M
In 1934 after the Nazi seizure of power, a program of re-armament was initiated. During this program, surplus Gewehr 98s were modified into two variants, refereed to among collectors as the Gewehr 98M and the K98b. This rifle is an example of the Gewehr 98M. The main differences between this and the standard Gewehr 98 is the addition of grasping grooves to the stock, the addition of a bolt take down disc in the stock, a replaced and wider rear barrel band (with a modified barrel band spring, and the replacement of the roller coaster rear sights to a K98k style of rear sight. The rear sight bears the code S/42G which indicates the rear sight was secretly manufactured by Mauser. It also indicates a re-work date of 1935. The rear barrel band also has a 1935 stamp on it. This rifle does not have the “1920” Reichswehr stamp, indicating it was one of the secret rifles hidden away after World War I. It is also not marked for Spanish use, as these sometimes were given to Spain. An interesting note of these rifles is that many went to various Units in the SS, most notable the SS Leibstandarte, Adolf Hitler personal bodyguard unit In almost any picture of the Leibstandarte in their infamous black uniforms, they are armed with Gewehr 98Ms.
M 98 magnum
John Rigby & Co. commissioned Mauser to develop the M 98 magnum action in the early 1900s. It was designed to function with the large sized cartridges normally used to hunt Big Five game and other dangerous game species. For this specialized type of hunting, where absolute reliability of the rifle under adverse conditions is very important, the controlled-feed M 98 system remains the standard by which other action designs are judged.[27] In 1911 John Rigby & Co. introduced the .416 Rigby cartridge that due to its dimensions could only be used in the M 98 magnum action.[28]
Paratrooper variants
YExperimental versions of the Karabiner 98k intended for the German paratroopers that could be transported in shortened modes were produced. The standard Karabiner 98k was too long to be carried in a parachute drop. However, the German paratroopers made only limited combat drops after the 1941 Battle of Crete; there was therefore little need for these rifles. Specimens with folding stocks (Klappschaft) and with detachable barrels (Abnehmbarer Lauf) are known to have been produced at Mauser Oberndorf.[8]
G40k
The G40k with a total length of 1,000 mm (39.37 in) and a barrel length of 490 mm (19.29 in) and 3.2 kg (7.1 lb) weight was a shortened experimental version of the Karabiner 98k.[8][24] The rear tangent sight of the G40k was graduated for s.S. Patrone cartridges from 100 m to 1000 m in 100 m increments. A batch of 82 G40k rifles was produced in 1941 at Mauser Oberndorf.[25]
Suppressed
A removable, muzzle-mounted HUB-23 suppressor, visually resembling the Schießbecher, was manufactured for the Karabiner 98k. After several suppressor proposals from the firearms industry and the SS-Waffenakademie (SS Weapons Academy), the HUB-23 was produced based on a design proposal by Unteroffizier Schätzle. The HUB-23 weighs 0.5 kg (1.1 lb) and is 180 mm (7.1 in) long. The maximum effective range of a Karbiner 98k with a HUB-23 mounted and firing special subsonic Nahpatrone (“near cartridge”) reduced load ammunition with a muzzle velocity of 220 m/s (722 ft/s) was 300 m (330 yd). The use of the HUB-23 suppressor and subsonic ammunition resulted in a sound signature reduction by 75%.[17] The HUB-23 suppressor and the special subsonic ammunition were mainly used by special forces units such as the Brandenburgers and snipers.[citation needed].
Schutztruppen Karabiner 1888
This specific example was manufactured in 1893 at the Erfurt arsenal. During World War I, the Kar88 was still in use by secondary units and colonial troops, including the Schutztruppe in German Africa. These forces often modified their weapons to suit harsh environmental conditions. This particular Kar88 was captured by British forces in Togo in 1914. It originally featured a curved bolt handle, but it was later replaced with a straight bolt. 
The invention of smokeless powder in the late 19th century immediately rendered all of the large-bore black powder rifles then in use obsolete. To keep pace with the French (who had adopted smokeless powder “small bore” ammunition for their Lebel Model 1886 rifle) the Germans adopted the Gewehr 88 using its own new Patrone 88 cartridge, which was also designed by the German Rifle Commission.[2] The rifle was one of many weapons in the arms race between the Germanic states and France, and with Europe in general. There were also two carbine versions, the Karabiner 88 for mounted troops and the Gewehr 91 for artillery. Later models provided for loading with stripper clips (Gewehr 88/05s and Gewehr 88/14s) and went on to serve in World War I to a limited degree. Unlike many German service rifles before and after, it was not developed by Mauser but the arms commission, and Mauser was one of the few major arms manufacturers in Germany that did not produce Gewehr 88s.[3]
