The main reasons for going to op-rod driven ARs in a select few units in the military was for SBR suppressed use, a lot of full auto, and the ability to adapt to different ammunition types in 5.56 NATO.
I'm unaware of similar testing and conclusions for 6.5 Grendel. You really need to engineer the system around the operating mechanism if you're going to go that route, which is what HK did with the HK416, which now has an adjustable gas regulator with the HK416A5 version.
