Honestly, you can tune the rifle for the suppressor. Without an adjustable gas block (no experience with piston guns) the shooter's ear will be roughly the same suppressed or un suppressed. If you properly adjust things, you can get an AR into the mid 130s shooter's ear, and I would expect lower numbers with buffer and spring tuning, along with the lower pressure of the grendel compared to 5.56. I've yet to see the gas face with a gas gun that has been tuned for a suppressor.
