The civilian world is flooded with 7.62NATO caliber Stoner-pattern rifles. Perhaps that’s where they should start looking ...

7.62x39 is a decent round (AK 47)
7.62x51 is more powerful (Nato)
A .308 is even more powerful

H&K has their HK433 but that is is a 5.56
Very good gun.

They have planned variants of HK231 and HK123

If they’d build the HK123 to handle a .308, that would be best, as you could fire a 7.62x51 in a .308 gun, but NOT visa versa

Do you arm your guys with the inferior, but battlefield plentiful AK round?
Or do you give them a plentiful, more powerful round?

A .308 gun allows use of the common 7.62 Nato round, that a lot of our allies might carry (if not carrying the 5.56)
But would not allow scavenging from adversaries using AK’s like those being used in the ME

The rifle won't matter that much. The Squad Automatic Weapon that'll have to go with it will.

I wonder if we're going to see a move to a .30 caliber cartridge based on the 45mm long 5,56 M193/M885 case. The .30 Blackout would seem to be the likely contender.
