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.
