AK-47 is a launch 762 39 mm M43 type intermediate-power automatic rifle, it uses the principle of air-guided automatic, rotary locking bolt, 30-round arc magazine, and can choose between semi-automatic or fully automatic firing. The design idea of AK-47 is based on the actual combat experience of the Soviet Union in World War II, combined with the battlefield environment at that time and the comparison between friend and foe, to meet the conditions of certain accuracy, range, and firepower intensity, to have high reliability and good environmental adaptability, and at the same time simple structure, low cost, easy to operate. The birth of the AK-47 is a compromise with the traditional rifle cartridge, and it is also a kind of foresight of modern warfare, which to a certain extent has changed the combat mode and tactical thinking of the infantry.
The effective range of the AK-47 refers to the maximum distance that can cause fatal damage to the target, and it is affected by a variety of factors such as ammunition, barrel, sights, climate, shooter, etc.
First of all, the performance of the ammunition determines the basic range and lethality of the AK-47, 7The muzzle velocity of the 62 39 mm M43 cartridge is 715 m s, the muzzle kinetic energy is 2100 joules, the effective range is 400 m, and the maximum range is 1000 m. The advantages of this ammunition are small recoil, small size, large ammunition carrying capacity, suitable for fully automatic shooting and fire suppression at close range, and the disadvantage is that the range and lethality are relatively weak, and it is not suitable for accurate shooting at long distances.
Secondly, the accuracy and stability of the AK-47 were affected by the length and mass of the barrel, which had a barrel length of 415 mm and a rifling length of 369 mm, rifling right-handed, a rifling pitch of 240 mm, and a chrome-plated barrel. The advantages of this barrel are that it is wear-resistant, corrosion-resistant, and easy to clean, but the disadvantage is that the accuracy and stability are not high, especially when firing continuously, the muzzle will produce a large jump, which requires the shooter to spend more time and effort aiming and adjustment.
Again, the type and quality of sights affected the aiming effectiveness and firing efficiency of the AK-47, which had a mechanical sight and was equipped with a night vision sight. The cylindrical crosshair at the muzzle and the U-shaped notched door of the gauge have reversible attachments, which contain the fluorescent material radium-221. The sighting gauge is divided into 100,800 metres, one is divided into 100 metres, and the combat gauge is set at 300 metres. The advantages of this sight are simplicity, practicality, and durability, but the disadvantages are poor accuracy and field of view, wind deviation correction is not possible, and the front sight guards are often mistaken for crosshair when shooting at night.
Finally, the climate and the shooter's technology and psychological state also affect the effective range of the AK-47, different temperature, humidity, wind speed, wind direction, etc. will have an impact on the trajectory, muzzle velocity, lethality, etc., while the shooter's posture, breathing, grip strength, pull, eyesight, mentality, etc. will affect the accuracy and effect of shooting.
Depending on the criteria and conditions, the effective range of the AK-47 can vary from 300 to 800 meters, but it is generally believed that the AK-47 will be able to perform at its best within 400 meters. At this distance, the AK-47 has a relatively straight trajectory, a higher muzzle velocity, greater lethality, higher shooting accuracy, and greater fire suppression. At this distance, the AK-47 is able to effectively hit enemies at close range, especially on complex battlefields, and is able to exert the maximum flexibility of the rifle. At this distance, the AK-47's low recoil means better control and accuracy for the shooter, especially when firing continuously, with less muzzle bounce and less time and effort for the shooter to aim and adjust. At this distance, the small size of the AK-47 means that the magazine capacity is large, the ammunition carrying capacity is large, and the shooter does not need to change and replenish ammunition frequently, which improves the persistence of firepower. At this distance, the AK-47 is powerful enough to not cause a waste of resources and ** expansion, and at close range, the enemy's movement speed and reaction time will be reduced, and the AK-47's fire suppression advantage will be enhanced, and even the enemy's firepower will be suppressed.
