Looks like a M70 to me:
Note folding stock (”A” variants), and the 3 slots on the foregrip.

Before Bosnian civil war started in 1992, Bosnian Muslim Patriotic League got in possession of 100,000 assault rifles from the Army and NG depots. Most were M70. I wonder if there are any AK-47 in Bosnia - there was no need for them when M70 was plentiful. Also, before civil war no one called M70 "AK" or "Kalasnikov". It is colloquial use by people who are not familiar with weapons, hence Bosnian media reports of "Kalasnikov rifle".
Yugoslav armament industry was copycat but capable of producing significantly improved originals - be it Mouser M98 Carbines (Zastava M48), Sig handguns (CZ-99), Dragunov sniper or AK-47. They improved even when under licence agreement (e.g. Zastava made Skorpion M84 submachine pistol)
