What size gas port is needed for a always suppressed 11.5 inch carbine gas barrel? I would rather not need an adjustable gas block. This will be in an AR.
I am ordering a PF 6.5 Grendel Criterion Barrel. Percision Firearms says they can drill the gas port to any size. But they recommended .90 for suppressed only use. Doesn't that seem big? I though I would want smaller for suppressed use.
