The 6.5 Grendel would be totally sick in the SCAR light. The SCAR heavy can stay in the tried and true .308
Sadly, we are part of NATO and that means we will probably stick with the .223 for a long time to come.
Unless we throw a huge party, invite all the decision makers from each NATO country, get em' REALLY drunk and make them decide that the 6.5 Grendel is the new NATO round! :lol:
