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

Seems like Grendel could be used in all 3 platforms and everybody could share ammo? 14" barrel with 80-100 grain ammo, 20" barrel scoped with 120-130 grain ammo, and a saw type platform. Really no need for a heavy machine gun. Maybe a dude with a bolt .50 for vehicles and bunkers.
