'Soldiers from the 101st Airborne Division at Fort Campbell, Kentucky, on Thursday became the first Army unit equipped with the service’s Next Generation Squad Weapon systems, officials said in a service release.

Troops with the 1st Battalion, 506th Infantry Regiment accepted the next-gen weaponry — the XM7 rifle, the XM250 automatic rifle, the XM157 fire control advanced optic, and the 6.8mm family of ammunition — in preparation for an equipment trainer course in April, the statement said.

The Army’s newest rifle and automatic rifle had already made it into soldiers’ hands for testing, but are now officially being fielded.'

Interesting. Just looking at the specs, it's a full pound heavier than the M4 and probably over 10 pounds fully dressed. That's a bit heavy for a field rifle (IMO).
They're also fielding a news spec of ammunition, to which I'm sure the DoD has secured the procurement of.
There are a lot of pluses to moving to a round better than 5.56mm, but a heavier platform naturally comes with that.
The bottom line: I hope the troops are happy with it.
