+1, there's no reason to go off the approved track. 0.136 bolt-face-depth dimensions are the way to go, plus those parts are much more interchangeable.
Dbl check with McGowen that they are indeed making your 6.5 Gr-AR barrel for:
1. SAAMI spec chamber - not "264 lbc" or "6.5 match-whatever" etc etc. The 6.5 Grendel SAAMI chamber has a compound throat angle to it, so McG should "roger" that for you on your barrel.
2. Set up for a bolt face depth of 0.136"
This will save you time and trouble in the long run IMO.
My 2 cents'.
