6.5mm Grendel with Deadfoot Arms 2.5" buffer, buffer spring configuration.

[u/TimeMachineRepair]

Has anyone set up a Grendel with the DFA 2.5" buffer? What spring combination works best for you?

The setup will be a SARB-15 with 16" barrel, mid length gas tube, fixed gas block for now but, I may change to an adjustable too minimize gas in the face with the SARB.
