More Info from AI;

The Arisaka Type 38 rifle (三八å¼Âæ©å…µéŠƒ, sanhachi-shiki hoheijÅ«) was a highly durable, 6.5×50mm bolt-action service rifle adopted by the Imperial Japanese Army in 1905

(the 38th year of the Meiji Emperor's reign). Designed by the prolific firearms designer Major Kijirō Nambu, it was a vast improvement over the earlier Type 30 rifle, simplifying its bolt design down to just six basic parts. It served as Japan's standard infantry rifle from its introduction through World War I and World War II. [1, 2, 3, 4]

Key Specifications & Mechanics

• Design & Action: Turn-bolt action based tightly on the rock-solid German Mauser G98 system. It is historically renowned for having one of the strongest receiver actions of any military bolt-action rifle ever built. [1, 2, 3]
• Calibre:Â Chambered in 6.5×50mm Arisaka. The cartridge offered light, pleasant recoil and flat ballistics, though it lacked the raw stopping power of larger Allied cartridges. [1, 2, 3, 4]
• Capacity:Â 5-round internal staggered box magazine, loaded via stripper clips. [1, 2]

Dimensions: Exceptionally long at 1,275 mm (50.4 inches), which reflected early 20th-century tactical doctrines emphasising volley fire and bayonet reach. [1, 2, 3]
