I have a bunch of C-Products stainless steel 25 round 6.8SPC magazines that work just fine with my 6.5 Grendel rifles. Nothing needs to be changed - the followers are identical for the 6.5 and 6.8 mags other than markings. I would recommend you look into an ISMI mag spring upgrade or similar, as some of the C-Products springs are weak and may cause misfeeds.
