The pronunciation of "ак" in Russian can be transliterated as "Aka", so it is wrong to read its Russian abbreviation in English.

1946, on the basis of his 7.62× 39mm м 1943 semi-automatic rifle with powerful bullets, Kalashnikov designed a sample gun (named акк-46) which can be fired repeatedly. The rotary lock gun he designed became the later designed ак. In the same year, I took the shooting range selection exam. After a series of tests, the air guide device and piston system were improved, and ак-47 was designed. After strict testing in sand and mud environment, it was selected as Soviet standard equipment in 1947, finalized in 1949, officially put into mass production, and produced in Izhevsk military factory. 195 1 year, the former Soviet army was equipped with semi-automatic carbine to replace simonov. In 1953 ак-47, the production method of shell is changed from stamping process to machining process. ак-47 began to equip a large number of Soviet troops. The AK-47 equipped by the Soviet Union was replaced by its improved AKM in the late 1950s. From 1950 s to 1980 s, ак-47 series is the standard equipment of the former Soviet Union and Warsaw Pact countries. 1After the ак-74 series with a diameter of 5.45mm was equipped with the former Soviet army in the 1980s, the ак-47 series with a diameter of 7.62mm gradually withdrew from the Soviet standard equipment (in fact, AKM has been used all the time, and it can be seen from the pictures of the second Chechen war that the Russian army used AKM).

ак-47 Semi-anatomical diagram ак-47 assault rifle belongs to automatic rifle. Compared with the rifles in World War II, the rifle has a shorter body and a shorter range, which is suitable for short-range assault operations. The air duct is located above the barrel, and the bolt is driven by the piston. Turn the locking bolt. 7.62mm caliber, firing 7.62×39mm M 1943 medium-power bullets, arc magazine with 30 rounds of ammunition supply capacity, safety/speed machine handle on the right side of the magazine, semi-automatic or full-automatic firing mode can be selected, and the pull handle is located on the right side of the magazine. The insurance of AK-47 is very distinctive. General assault rifles are "safe, semi-automatic and fully automatic" from top to bottom, while ак-47 is "safe, fully automatic and semi-automatic". When dealing with emergencies, soldiers always pull the reducer to the end, pull the trigger and shoot all bullets, while AK-47 only shoots one bullet, which greatly saves bullets and improves safety. The bolt of ак-47 works reliably, and its mechanical structure can ensure its continuous work even if foreign objects such as dust enter the gun continuously. It can also maintain quite good performance in extremely harsh environments such as desert, tropical rain forest and severe cold. It is said that in the Vietnam War, it was put into the water for several weeks, then it was taken out of the water and loaded with bullets. It can still shoot. Moreover, it has large firepower and is suitable for close combat. Simple structure and easy decomposition; Easy to clean and maintain, good service; Simple operation. The main disadvantages of ак-47 are that the muzzle jumps seriously during automatic shooting, the back seat of the gun rack hits the bottom of the shell, and the short barrel leads to a short aiming baseline, and the design of the sight is not ideal, which affects the shooting accuracy. It is impossible to guarantee accurate shooting beyond 300 meters, and the shooting accuracy is even lower. Moreover, the AK-47 is far away, nearly 2 meters. In fact, it can meet the requirements of short-range assault operations with encounter as the main task

The improved акм (втоматкалашнир) is in 1959. Its muzzle is obliquely cut to achieve the effect of muzzle brake. At the same time, materials are further synthesized by stamping and welding processes, so that the weight is reduced, the production cost is low, and mass production is facilitated. The failure rate is very low except that the hour hand is occasionally broken when disassembling the shell.

ак-47 series rifles became famous in the Vietnam War in the11960s, and ак-47 and its China imitated the North Vietnamese regular army and guerrillas on a large scale. This automatic weapon is trusted by soldiers in the jungle environment. During the Vietnam War, it is said that many American soldiers abandoned the heavy-duty M 14 automatic rifle or the frequently-broken M 16 automatic rifle which was not suitable for the harsh conditions in the tropical rain forest, and used the ак-47 rifle captured by Vietnamese soldiers instead, just because the ак-47 series rifles were extremely reliable, easy to control and had intensive firepower.

The Soviet Union exported ак-47 series rifles and their manufacturing technology to all parts of the world. ак-47 series rifles are widely used by the military or anti-government forces in many third world countries and even western countries because of their amazing reliability, simple structure, durability, good quality and low price, and flexible and convenient use. In some areas, all parties to the conflict are happy to use а-47. In addition, many countries in the world have carried out imitation or licensed production, including East Germany (imitation model Mpi-47), the former Yugoslavia, Hungary, China (China imitation model has long been called Type 56 assault rifle), Poland, Romania, Bulgaria, Egypt, Cuba and North Korea. 2 1 century is still in production. The design idea of ак-47 has also influenced the design of infantry light weapons in Israel, Finland, China and other countries, such as Israel's Galil assault rifle and China's 8 1 automatic rifle. ак-47 series rifle is one of the most widely used rifle weapons. Its breadth may only be comparable to that of Mao Se rifle and Colt revolver in the history of light weapons. Kalashnikov, on the other hand, is also known as the "world gun king" because of the wide use of ак series rifles in the world.
