AK-74 assault rifle is a 5.45 x 39 mm assault rifle developed by the Russians in the early 1970s through numerous tests to improve the Kalashnikov and changed its caliber from 7.62 x 39 mm to 5.45 x 39 mm, 50%. They also manufactured a good bounce rate, mounted on the gun nozzle and proved to be effective in relieving rebound. In 1974, this weapon was brought into active service in the Soviet army as a major individual weapon. This weapon was seen in 1977 as part of the Soviet infantry and naval forces, especially during the Afghanistan war. The bounce rate is very effective and works to convert the pressure pushing the crossover up to the sides, which increases the ability to control the weapon well at the automatic launch, as opposed to what is in the Kalashnikov. One of the disadvantages of this weapon is that there is a very strong voice on both sides, because the pressure that should have been on the top has shifted to both sides. This gun is called the AK-74 if the pod is fixed, and the AKS-74 is called if it is collapsible
