6.8mm vs 5.56x45mm

Ok, I've heard of this upgunning of the US M16 and M4 series for a while now, but is it going to happen anytime, or is it just wishful thinking?

At this point? Wishful thinking. DoD is not embracing the idea. SpecOps has played around with it though.

As far as I know (and I certainly don't know everything), all of the new proposed assault rifles for the US military are still sticking to 5.52mm 7.62mm NATO rounds; even the H&K XM-8, the Alliant Techsystems XM-29 OICW, and the still-born Fabrique Nationale SCAR, were all developed in 5.52 and/or 7.62mm.

And its a shame.... The 6.8 is a hell of alot better cartridge.... Too bad theres a surplus of 60 million rounds of 5.56.....

I think you mistyped, Les. You mean 'billions'.
