More powerful than the M16A1 but with shorter range. Both the gun and its 7.62mm ammo are very common and you can afford to equip most of your squad with them. While it is a staple midgame weapon for gun-toting characters, it gradually loses its effectiveness towards endgame as heavily armored enemies become more common.
The AK-47 is a simple assault rifle of Soviet origin, invented by Mikhail Kalashnikov in 1947 and adopted by the Soviet Army in 1949. AK-47s were manufactured across the world during the second half of the 20th century through the beginning of the 21st century. In 1956, AK-47s were adopted by the Chinese Army (PLA) but were replaced with new-generation assault rifles prior to the Great War.
After the Great War, AK-47s were produced by different workshops and remaining factories throughout the Wasteland, but by some coincidence were not seen in the West Coast, within the NCR limits, nor in the Capital Wasteland.
