What is the effective range of an AK-47?

Answer 1

After the Great Patriotic War, the Soviet Union realized that modern and future combat for enlisted soldiers would consist of a range less than 300 meters. Therefore, it was deemed a waste in resources to produce a rifle for longer ranged combat. (Targets over 300 meters was designated to snipers using more powerful and more accurate rifles)

Thus, the AK - 47 was designed and produces to be the most accurate and reliable weapon for combat up to 300 meters.

Fairly inexpensive and able to function in the most adverse conditions, the AK was and still is the weapon of choice for many countries - the most widely used assault rifle in the world.
