On Czech light machine guns equipped by China and Japanese crooked light machine guns in World War II.

The Czech light machine gun equipped by the China army and the crooked light machine gun equipped by the Japanese army in World War II have their own characteristics:

Czech light machine gun was a famous gun during the Anti-Japanese War. The shape of the gun is special, angular and stereoscopic. Czech light machine gun is also a weapon widely used by the Eighth Route Army and the New Fourth Army. This weapon was widely used by the Red Army, the Eighth Route Army (the New Fourth Army) and the People's Liberation Army from the beginning of the anti-encirclement campaign to War of Resistance against Japanese Aggression and the War of Liberation. It is the main light machine gun that equipped our People's Liberation Army nearly ten years after liberation.

The gun uses the gas produced by propellant combustion to push the bolt to finish shell withdrawal, reentry, loading, locking and firing. Due to the excellent performance of Czech light machine guns (the muzzle velocity of bullets is 830m/s, the maximum range is 1500m, the effective range is 900m, and the firing rate is 550 rounds/min), Czech light machine guns are equipped in many countries and have a large number of configurations, which occupies an important position in the history of firearms in the world.

Second, the bent handle light machine gun equipped by the Japanese army: commonly known as "bent handle", describes the essential characteristics of the Japanese 6.5mm light machine gun. Japan's 6.5 mm light machine gun adopts a "neck" similar to the butt of a traditional rifle. At the same time, because its aiming baseline is biased to the right of the gun surface, in order to prevent the user's neck from leaning too far to the right when aiming, the already slender neck is bent to the right, so that the position of the gun butt can meet the aim of the gun against the shoulder.

Performance of light machine gun with inclined handle: the initial velocity of the bullet is 736 m/s, the maximum range exceeds 1500 m, the effective range is 600 m, and the firing rate is 600 rounds/min.

At that time, the crooked light machine gun was the only light machine gun equipped by the Japanese army, which had three characteristics:

1. In the automatic mode, the "light machine gun with inclined handle" adopts the air-guided working principle (the high-pressure air generated by bullets is the air source for the gun to unlock/latch, unload the shell and supply ammunition), and the overall structure and action principle of its automatic mechanism parts are basically the methods generally adopted by machine guns in the world at that time and even today.

2. A loader which looks like a "funnel" and can load 6 magazines (30 rounds in total) from above is adopted.

3. Being able to use the 6.5 mm bullets and magazines of the March 8th rifle deployed by the Japanese army at that time (5 magazines can be loaded, and 30 bullets can be fired in succession) and one bullet can be fired, thus avoiding the disadvantages of chaotic ammunition and various transportation types.
