Prototype 7.7mm Arisaka Type 99 Carbine (ad-free)

The Japanese military made the decision to move form a 6.5mm infantry rifle to a more powerful 7.7mm cartridge in the 1930s, with specifications for the new rifle proposed in 1938. In response, the Nagoya and Kokura Arsenals developed new models of rifle and carbine.  

What we are looking at today is one of the Nagoya (Plan #1) experimental carbines; serial number 4 to be specific. It has a variety of novel features, including:  

Spring loaded buttplate for recoil reduction 

Unique muzzle brake 

New aperture rear sight 

Threaded cleaning rod 

New magazine retention system 

ecoil bolt in stock  

These carbines, and the other experimental patterns, were tested at the Futsu Proving Ground in 1939. Elements of both designs were ultimately used to create the Type 99 adopted later in 1939 (Japanese calendar year 2599).

What a cool story! My great uncle was tasked with destroying war material in Japan after the war. He brought home about 2 dozen Arisakas, sadly I only got to play with a couple. He saw them as free hunting rifles, not as artifacts. I shot the 7.7 mid length significantly. The 6.5 carbine is tiny, and super handy, but almost impossible to get or make ammo for.
