New Marine Corps weapon to replace SAW

...What I said in my 2005 magazine article is that the 6.8 SPC case dimensions appear to be far more compatible with the M27-type link configuration than is the shorter 6.5 Grendel case. The result is that it would necessarily be more difficult to design a viable link for the Grendel case. These are demonstrable facts, not conjecture.

These may very well be facts, but it doesn't mean they're worth the paper they were written. Their meaningless other than to demonstrate that disintegrating links can and will work on a short rifle cartridge.

No one has ever claimed that the M27 link would work if you just took a pair of pliers to them.

Of course the links need to be designed specifically for the Grendel. You have 2 engineers here, one with extensive experience (JASmith), telling you that this is a straight forward simple engineering process. This isn't putting a man on the moon.

The only reason that it hasn't been done is that there is no business justification for doing the work.
