Port Pressure

[Jaywalker]

How does the port pressure of the Grendel compare to the 5.56 when used in rifles with equal barrel and gas system length?

I don't know any numbers, but judging by the lower chamber pressure and larger gas port on the Grendel with similar length barrels and gas systems, I'd say that the port pressure is lower as well.

Thanks, I didn't know the gas port was bigger.
