I would like to see a Six8-type receiver set made for 6.5 Grendel. However, I have to question the idea that 6.8 P-Mags would work well with 6.5 G cartridges. IMO, a Grendel-specific P-Mag would be needed.
Six8 P-Mags were designed specifically for the 6.8 round, which has a case diameter ~0.020" smaller than that of 6.5 Grendel. I think that will almost certainly result in improper cartridge stacking when inserting the fatter rounds into the magazine, which will in turn cause other problems (bulging magazine, unreliable feeding, etc).
