Amend2 polymer 6.5 grendel mags

[Nabby]

I would love a polymer Grendel mag and will definitely pick one up when there's a -5 available so I can hunt with it. It's nice to see such a thing coming, but I am going to sort of 'wish out loud' that these might someday be available in a translucent poly like those Lancer mags. My roomie runs those in his Blackout and they're pretty great. I'd certainly pay a little extra for the feature.
