Serbia adopting 6.5 Grendel as main military cartridge

[VASCAR2]

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. Curious if a civilian version of the Zastava will ever be imported into the US.

Would the Zastava magazine work with AR-47 from PSA that accepts AK mags. The AR-47 in 6.5 Grendel might be an interesting combination if the Zastava 6.5 Grendel is a quality mag.
