Can someone with a metal Grendel/ARC mag (Stoner or similar, ASC) take an accurate measurement of the inside, between the ribs, for me?  I have some coming and working on a follower project but wanted to get a head start.  I have 25 rounder's coming, but I'd think that would be consistent on smaller mags as well.

TIA, Rod.

As do I, ha.  When I do the math on the numbers that I have been able find, I get .770"ish so will probably run with that.  Maybe reduce a 100th for breathing room.
