Grendel Magazine for Prone shooting

[VASCAR2]

I saw yesterday where ProMag is selling a 27 round 6.8 SPC magazine. Midsouth Shooters supply list this ProMag as being able to shoot 6.8 SPC or 6.5 Grendel. Midsouth is also selling E-Lander magazines as being compatable with 6.8 or 6.5 Grendel. I’m not intersted in ProMag as they don’t have the best reputation but I was unable to find any additional vendors who are selling 6.8 SPC labeled E-Lander magazines.

I have not purchased any of the C Products Defense 6.5 Grendel magazines.
