Does the 6.5 grendel have the potential to replace the 5.56 for the military?

i'm pretty sure you could build a belt fed 6.5 fairly easy using the com block links for the 7.62x39

I'm equally sure that could be done. See: http://www.65grendel.com/forum/showthrea...1#post9998

The problem is, the US Armed Forces only use disintegrating links, and neither the M13 (7.62) nor the M27 (5.56) links fit the 6.5 Grendel case properly.


Because of the Grendel case dimensions, it'll be necessary to design a new link specifically for the 6.5 cartridge. If it's doable, I expect it would look less like the M13/M27 design (above), and more like this one developed for 9x19.

i suspect a new round is in the works with a lot of new arms to go with it-- i just hope it ain't some case-less ammo involved--

I dunno if there are "a lot of new arms" in the works, but a new carbine is reportedly being developed to fire new 6.5mm polymer cased-telescoped ammo (CTA), with a 6.5 CTA LMG being considered for possible future development.
