Serbia adopting 6.5 Grendel as main military cartridge

Sounds like something for the Specijalna brigada, rather than their regular army units.

Sounds like they wanted a more modern modular assault rifle system than the older Kalashnikov-based rifles that are basically obsolete in the 21st century, without full redesign for interface with modern accessories.

All of which is what I understood the 6.5x39/7.62x39 M17 modular rifle system was intended to do.
