Has anybody found any current production 5.56 ak mags that an 84s will feed reliably from?

I’ve heard the polish gn radom mags work tho I haven’t tried it as my rifle hasn’t arrived to my ffl yet

Mine worked flawlessly with most AK 74 mags, as long as I only loaded 25 rounds or less. I believe the Bulgarian circle 21 magazines would not insert at all, but practically every other AK 74 mag worked fine. Years ago there was a user at gunsnet who posted a tutorial on how to trim the follower to make AK 74 mags reliably feed when fully loaded. I never did the modification because I was satisfied with loading 25 rounds.

Good luck. I wish I still had mine.
