So I've been trying to figure this out and I haven't seen the plain answer that I have been looking for (I am possibly blind though too). Do I need specific grendel mags for my AR or can I run them out of 5.56 mags? It sounds like there are regular feeding issues with most of the poly mags but metal mags feed well usually? Everyone local that I've talked to knows almost nothing about grendel so I'm left high and dry.
