Furry

This article is a great example of why I hate Grendel fans.  Lying with the facts is still lying.

The author hates the AR because of its gas system.  Um, show me a Grendel gun that's not based on the AR.

The 6.8 is better than an M4, but it doesn't fit in an AR magazine.  Really?

Which one is the 5.56 magazine?

The author also implies that 6.5 works in a USGI magazine.  It doesn't, for the same reasons that 6.8 doesn't.

He impugns the M249 in his article too.  While advocating the 6.5 he's also forgetting that there hasn't been any belt fed development of the round.  Bill Alexander has openly stated that he wasn't interested in that road and gave no consideration for accommodating links.  As far as I know, there's been no work to adapt 6.8 to a belt gun either.  I stand corrected.

In all honesty, he gets one thing right while not realizing it.  To really fix the problem, you're going to have to issue a whole new weapon, not one derived from and compatible with the M16 family.  A totally new round with totally new magazines and belts in a totally new rifle and SAW are what is needed.  Designing them together would be the ideal way to do it.  Being constrained by the dimensions of the M16 magazine is a severe limiter on developing a new cartridge.  It makes a lot of economic sense for commercial sales to we armchair heroes, but they are a kludge at best for an issue infantry rifle.
