The history of the development of firearms goes back a long way. In 1132 A.D., a prefect named Chen Gui used the firearms he developed to form a 60-person musket team when he led the De'an army and civilians to fight against the Liukou, and every 2 people used a musket to beat the Liukou to the worst, which was the earliest application of firearms in war.
Subsequently, in 1259, China first invented a fire assault gun made of bamboo and fired small projectiles with black powder, and since then, the most important hot weapon in human history - firearms, has been born.
And after the gunpowder invented in our country was transmitted to the West, about the 14th century, a musket gun that communicated with the chamber through the tail of the barrel appeared in Europe. However, there were too many disadvantages of this class of firearms - too low rate of fire, extremely poor accuracy, and a close firing range.
Over time, by the 15th century, the Spaniards invented the arquebus. These firearms are loaded with black powder and lead pellets from the muzzle, and the ignition mechanism is a simple C-shaped hook with one end fixed to one side of the butt and a slow-burning rope sandwiched at the other end, which can be fired by simply lighting the rope. However, the disadvantages of this type of firearm are still obvious - they are highly susceptible to the elements, they are easily exposed during night combat, and flying sparks can easily injure the user.
By the middle of the 17th century, many European armies were generally equipped with flintlock pistols, which lasted for more than 200 years until 1848.
In 1860, the United States was the first to pioneer a rotary barrel gun.
At the end of the 19th century and the beginning of the 20th century, the development of firearms entered a new stage. With the continuous advancement of technology, the design and manufacturing technology of firearms has been greatly improved.
During this period, a number of landmark firearms appeared. For example, in 1898, the Mauser brothers, who were Germans, designed the first gun that fired smokeless gunpowder, the Mauser rifle. This rifle featured a rotating pull-back bolt, which had a high rate of fire and accuracy, making it one of the most advanced rifles of its time.
At the same time, the advent of automatic ** also marked a new stage in the development of firearms. In 1883, the British Maxim invented the world's first machine gun, which was fed by a chain of bullets, with a high rate of fire and continuous firepower, becoming one of the most lethal at that time.
During the First World War, the Germans invented the world's first assault rifle, the MP18 submachine gun. This rifle has a high rate of fire and good portability, and is able to quickly strafe enemy infantry groups.
By the middle of the 20th century, with the continuous development of technology, the design and manufacturing technology of firearms has been further improved. For example, the advent of AK47 and M16 automatic rifles marked the maturity of modern firearms. Among them, AK redefines the assault rifle, while the M16 automatic rifle is made of aluminum alloy material, which has a low weight and good portability, and at the same time adopts a conductive automatic method, which has a high rate of fire and accuracy.
