Google is your friend.
As usual there is the typical junk info being put out by people speaking outside of their wheel house.
Been a good 14 years since I went through my AK phase.
Short recommendation, get a 545, an ultimak(red dot), a blackjack, and a solid stock.
Owned a 762SAR, sold it, regret it somewhat
Still own a 545, vz58, and a Galil556
