The Army May adopt is as a specialty round but it would have to be adopted by NATO as well in order for widespread adoption.

So is the guess a 6.5 Grendel or a 6.8 SPC or something completely new?

Will there be a whole new platform or will they re-barrel current M4's?

Inquiring minds want to know...

115gr @ 2650ft/s is a badass round.
8mm will go appx. 2600 FPS with a 198gr projectile, and nearly 3000 FPS with a 150 grain projectile... the standard 7.62x51 round go's appx. 3000 FPS, and I doubt the 6.8 will penetrate as well as the M80A1. Not to mention the army has about a trillion rounds to get rid of...

From what I've read, they can use the same mags with the 6.8. But that's a shit load of M4's to re-barrel. A lot of reserve units still have M16A2's, I don''t see this happening in 4 years, way too much money involved.

Not really. It would cost about 2-3 billion to totally replace every M16 and M4. If you replace all of the SAWs it's another 500 million. That's chump change in DOD terms.

The new rounds will be more like shotshells than traditional brass cased rounds= less weight, less cost. The M16 is due for a replacement. The M16 has been being in service in some form for 50 or 60 years.
