Questions & Answers
Do these work with 6.5 Grendel?

Yes, and does well with 6.5 Grendel (and okay with .338 ARC). The case is the same size as 6.5 Grendel at the base, and only vary in actual bullet sizing. Other ARC magazines handle both 6.5 Grendel and 6mm ARC, too. Issues usually happen when you try to load more than 15 rounds or so into a magazine. The bend in high-capacity ARC magazines can cause misfeeds. Since this magazine is straight, it feeds well for all 20 rounds.

Flat black mag, with no markings as pictured. Good quality mag that runs well, but I did expect to see the pictogram painted on as pictured.
