The AKM (Russian: Автома́т Кала́шникова модернизи́рованный "Kalashnikov's Automatic Rifle Modernized") is a Soviet 7.62×39mm assault rifle, designed in 1950s as the major improvement from the earlier AK-47. The main distinguishing features of the AKM are its stamped receiver (visible rivets) instead of heavier milled one, slanted muzzle brake, and straighter fixed buttstock profile. Its design was copied and manufactured by various Soviet satellite states, such as the Hungarian AMD-65 and Yugoslav Zastava M70.
