New Marine Corps weapon to replace SAW

But then, when you confuse your own speculation with a hard conclusion that the Grendel is incompatible with links, you cross a line.

It is no where near a proven fact, yet the reader is led to believe your speculation is a fact.

Reading comprehension. I NEVER said the Grendel is incompatible with links. I said that designing a link for it would not be as simple as for 6.8 SPC.

The dimensional differences between the M27 link design, the M249 feed pawls, M249 feed tray cartridge stop, and the 6.5 Grendel case dimensions are not speculation; they are measureable, and clearly not conducive to a simple change in link loop diameter, as was done with the 6.8 SPC.

That is line that must not be crossed in the engineering and scientific world.

Actually, the line that should not be crossed in the engineering and scientific world is to say, "Even though there is no evidence that it's true, I want it to be true, therefore it is true."
