What 6.5 Grendel Magazines Are Best?

[StoneHendge]

Duramag 20 rounders came in today.

I think the rather hard curve to them looks a bit silly but if they work fine, that won't matter.

Thanks for the advice guys.

I don't know if the curve is completely necessary for feeding, but it keeps it completely clear of the ground when shooting prone off an Atlas bipod at the lowest setting. I also like the way it pinches into a support bag when shooting off of barricades, etc.
