Since the MDR and MDR-C are designed to accept both M16 and SR25 magazines (already planned to accommodate 5.56, ,300 BLK, 6.8 SPC, .308, and 7.62x39), it seems to be a more flexible platform for the Grendel magazine project.

I think we'd all agree with this. However, there won't be a lot of us that can afford that option.
