what size bullet does an ak 47 shoot
Comparison of the AK-47 and M16 The AK-47 was finalized, adopted and entered widespread service in the Soviet Army in the early 1950s.[27] Its firepower, ease of use, low production costs, and reliability were perfectly suited for the Soviet Army's new mobile warfare doctrines. More AK-type weapons have been produced than all other assault rifles combined.[28] In 1974, the Soviets began replacing their AK-47 and AKM rifles with a newer design, the AK-74, which uses 5.45×39mm ammunition.
