Prototype 7.7mm Arisaka Type 99 Carbine
This prototype 7.7mm Arisaka Type 99 Carbine represents an early attempt by Japan to develop a more powerful service rifle. Despite innovative recoil reduction features like a muzzle brake and spring-loaded buttplate, trials in 1938 found it unpleasant due to excessive muzzle blast and recoil. This led to the abandonment of the carbine concept in favor of the 'short rifle' design.
