Mags for longest OAL?

[Blazin]

What 6.5 Grendel mags will allow the longest OAL? Really hoping to find a mid-length one (approx 14-15 rounds). Appreciate any help.
Currently running C-Products mags, but eyeing ASC stainless steel ones.

My CProducts mags seem to allow the longest COL, slightly over 2.300". Not sure how big of a difference it really makes, as I'm of the opinion that you really need 2.400" to really capitalize off of case capacity and projectile location relative to the neck-shoulder junction. The AR15 magazine well is 2.395" +/- FAKEAR-15 tolerances.

Thanks for the feedback.
