Serbia adopting 6.5 Grendel as main military cartridge

[stanc]

I’m kind of curious about the magazine which appears to hinge in the same fashion as a standard AK-47 mag. Curious if this mag would work in the VEPR 6.5 Grendel. Would the Zastava magazine work with AR-47 from PSA that accepts AK mags.

The Zastava M17 receiver is basically AK, and I don't see the Serb military fielding new 7.62x39 mags that aren't interchangeable with their existing 7.62x39 mags.
So, I think it's very likely that the 6.5 G mags would fit any rifle that accepts standard AK 7.62x39 mags.
