The closing remark probably explains it all.
The companies include SIG Sauer, FN America, Textron Systems, General Dynamics and PCP Tactical. FN is submitting two variants.
I'm sure they will have a record profits and then probably in 30 years the story will be that the 6.8 doesn't meet all the needs of modern warfare; we need a powerful, long range round and something something for short distances in urban combat. That's how things go.
That's what I'm thinking. The sheer cost of the change is astronomical.
