6.5 x 40 New AR varient

[cory]

It is not a rumor. It's a verifiable fact that the (5.56mm) M27 link, although its loop diameter can be easily increased to fit the fatter Grendel case, does not allow sufficient case protrusion from the front link loop for proper interface with the front feed pawl and feed tray cartridge stop of a belt-fed machine gun. On the old Grendel forum, I posted a photo that illustrated the problem.

No one has yet shown that a viable disintegrating link can actually be designed and developed for the 6.5 Grendel cartridge.

Yes, and even before that guy, horde member RangerRick demonstrated the compatibility with RPD belts in the Grendel LMG thread: http://www.65grendel.com/forum/showthrea...1#post9998

That's fine for the European armies which use non-disintegrating link belts of the RPD type. Unfortunately, it's quite irrelevant to the disintegrating links used by the US military.

Well my little sister's pants don't fit me. That doesn't mean that I can't go to the store and buy a pair that does. What you're telling me is we need to make RPD links out of a material that will disintegrate, correct? That's a minor ED (Engineering Drawing) detail, that the M&P (Material & Process) team will deal with.
