Designing a Grendel IAR

[Variable]

I think the whole concept of an IAR (mag fed) is flawed due to capacity limitations, even with reliable drum mags. Linked is really the way to go with the duty position.

What I see with the Russians is that they love 45rd RPK mags, but you don't see the RPK used much at all, while you do see the PKM as one of the most important weapons at the dismount level.

Agreed as usual. I'd rather rock a belt. I guess we always come back to IARs because it's easier to acquire something like that in the civvy world.

I sort of envision a narrow engagement window where an IAR would be simpler and handier, but since the real world doesn't feel constrained to that narrow window, I'd default to a belt-fed where and when I could.
