Hmm... Does the XM25 and XM307 share the same projectile family, just with different length cases ala the M203 & Mk19? Or are they completely different rounds?

I've heard the SCAR will also be available in a 7.62mmx39 version that will accept standard AK magazines.

Anyword if the new rifle project will be looking at alternate calibers such as the 6.8mm SPC or 6.5mm Grendel?
