AK-47
Guns of Soviet Union (Russia) 
AK-47 (abbreviation Avtomat Kalashnikova 1947, Russia: Автомат Калашникова образца 1947 года) is an assault rifle designed by Mikhail Kalashnikov, produced by the Russian arms maker IZhMASh, and used by many Eastern Bloc countries during the Cold War. This rifle was adopted and used as a Soviet standard rifle in 1947. [2] When compared to the rifles used during World War II, AK-47 has a smaller size, with a shorter range, using bullets with a smaller 7.62 x 39 mm caliber, and has a selective-fire option. The AK-47 was one of the first assault rifles and is by far the most widely produced assault rifle.

Background design Edit
In World War II, Germany created the concept of assault rifles. This concept is based on the experience that modern combat is more prevalent at a short distance of about 100 meters. The power and reach of the bullets at that time turned out to be too large. Thus, the Germans began to develop bullets and submachine guns (many magazen contents and can be full-automatic shot) with bullets that range up to 300 meters. Taking into account the cost of production, this was achieved by shortening a 7.92 x 57 mm Mauser bullet to a size of 33 mm ie 7.92 x 33 mm Kurz (Kurz means short).
The end result, Sturmgewehr 44 (StG44), is not the first rifle to use this concept; previously Italy and the Soviet Union had designed a similar concept. However, Germany was the first to mass-produce their rifles. The Germans used many of their new rifles to confront the Soviets on the Eastern Front. The Soviet experience against Germany influenced Soviet doctrine in the following years.
Under Soviet doctrine, Mikhail Kalashnikov began thinking of the design of his rifle since the hospital, after being wounded in battle at Bryansk. He was informed that a new weapon was being searched, to be used with a 7.62 x 41 mm bullet made by Elisarov and Semin in 1943. But that time, Kalashnikov's design was defeated against Sudayev's design, PPS43. Kalashnikov changed his first design after he studied StG44 Germany in 1946. Because his design was quite impressive, Kalashnikov was chosen to lead a design team.
Design concepts Edit
Although similar, Mikhail Kalashnikov denies that the design was made based on the German StG44. AK-47 is more accurately said to be a mixture of innovations in previous years. For example, the AK-47 mechanics are more like M1 Garand than German rifles. Double locking lugs, unlocking raceway, and similar American design-like trigger mechanisms. [4] This is a natural thing, given that millions of M1 Garand have been successfully used in all corners of the globe. Although mechanically similar to M1 Garand, the concept of bullets, component layouts, gas systems, and AK-47 assembly methods are clearly similar to StG44. [5]
The AK-47's genius is, that the design is most appropriate for mass production. So the AK-47 managed to combine the benefits of M1 Garand with StG44, and could be produced quickly by the Soviet Union at the time.
Development of receiver Edit

Initially the production of the receiver (the part of the rifle that contains the firing mechanism) encountered many problems. The first production model used a receiver made of metal sheet metal stamping. The problem encountered was the difficulty of welding railing guides and ejectors, which eventually led to a lot of resistance. [6] But this problem did not stop production, as a solution, the metal stamping receiver was replaced with a machined receiver (shaped with a special machine tool). [7] This process is more expensive and weighty. so much his information
