The Type 99 Rifle (From the Japanese 九九式小銃 or 九九式長小銃 Kyuukyuu-shiki syoujyuu or Kyuukyuu-shiki tyousyoujyuu) was a bolt-action rifle of the Arisaka design used by the Imperial Japanese Army during World War II.
History
One of the Type 38 rifle's disadvantages was that the small caliber (6.5x50 mm) bullet it fired was not considered effective enough as an anti-material round[citation needed]. The Imperial Japanese Army (IJA) developed the Type 99 based on the Type 38 rifle but with a caliber of 7.7 mm. The Type 99 was produced at nine different arsenals. Seven arsenals were located in Japan, with the other two located at Mukden in China and Jinsen in Korea.
The IJA had intended to completely replace the Type 38 with the Type 99 by the end of the war. However, the outbreak of the Pacific war never allowed the army to completely replace the Type 38 and so the IJA used both rifles during the war. As the war progressed, more and more cost saving steps were introduced in order to speed up production. Late war rifles are often called 'Last Ditch' or 'Substitute Standard' due to their crudeness of finish. They are generally as crude as the 1945 dated Mauser K98k of Germany.
The Type 99 was produced in four versions, the regular issue Type 99 Short Rifle, the Type 99 Long Rifle (a limited production variant) and takedown Type 2 Paratroop Rifle and the Sniper Rifle Type 99. The standard rifle also came with a wire monopod and an anti-aircraft sighting device. The Type 99 was the first mass produced infantry rifle to have a chrome lined bore to ease in cleaning. All of these features were deleted by mid-war.
Design
The Arisaka, like the 1903 Springfield rifle, was based around the basic German Mauser design, albeit with some local alterations. It utilized a cock-on-closing action, which improved the rate of fire from the standard Mauser cock-on-open design. It featured a quick-release bolt and antiaircraft sights, as well as a rotating bolt cover and monopod. The bolt cover, in particular, was highly problematic. Many soldiers simply discarded them. The original versions are generally considered to be very strong rifles, having one of the strongest receiver assemblies of any military rifle of its time. As a bolt action rifle, the Type 99 was a very solid weapon, but was completely outclassed by the semi-automatic rifles deployed by the Allies in that theatre of war.
The Type 99's bayonet was in the form of a very long, slender blade, grooved to provide rigidness. The early models featured a hooked quillion. These bayonets attached to a lug under the barrel and were further stabilized by a loop that fit around the muzzle. Unmounted, it handled similar to a machete.
