US Army Considers Adopting an Interim Battle Rifle in 7.62NATO: eventually adopt 6.5

[stanc]

The pushback is going to be immense when units start experimenting with this.

Yeah, I would imagine so. It ought to be interesting.

SOCOM has zero plans to go that direction, that's for sure.
They're just going to more integrally suppressed 5.56 uppers with the SURG.
6.5mm Sniper Support Rifles (Semi Auto)
6.5mm LMGs (called an Assault Machine Gun)

Why are you sure SOCOM does not have such plans? Page 10 of the NDIA presentation shows an Intermediate Caliber Sniper Rifle/Carbine.
To me, that sounds more like an M110 SASS-type sniper rifle and a "battle carbine" (for want of a better term), than a sniper support rifle.
That they want an Intermediate Caliber Carbine makes me think it's basically a 6.5 version of the ICSR...or the battle rifle they currently use:
