Hmm actually this is kind of interesting.
A SCAR heavy in 6.5 creedmoor is kind of like a updated 21st century version of the EM-2 or the prototype .280 British FALs from the 1950s.
Personally I think this is very exciting, I think a round like 6.5 creedmoor or 6.5 grendel or .264 USA really makes sense today and we might even see a revival of sorts of the battle rifle.
With modern variable power optics and barrel manufacturing and the training professional armies of today a riflemen can actually exploit a longer ranged cartridge where the conscript armies of WW2 and the cold war could not.
Combine that with not having to reduce recoil for full auto fire on shoulder weapons, a polymer or hybrid casing to bring down ammo weight, and having to rely on small arms more at range with the restrictive rules of engagement in modern conflicts and honest to goodness a battle rifle suddenly becomes viable. If ammo polymer cased ammo becomes a thing, I will most def run whatever 6.5 Creedmoor Iteration of the SR-25 that SOCOM runs as my primary rifle
Funny how we came full circle to the old battle rifle concept and what is old is new
