I starting to lose the point of this thread. Wasn't this thread started in order to find a polymer mag for the Grendel and not to redesign a metal mag? I for one use ASC 6.5 and PRI 6.8 Mags with no problems at all. Personally I like the PRI Mags the best and never had a malfunction with one in over 5,000 rounds fired using 15 round PRI mags.
