Lightbulb Quick question about safety....

I have a .300W upper I built up specifically for subsonic, it has a .093 gas port in the pistol position and cycles the subs FLAWLESSLY.

Ok, now I want to load up some supersonic rounds and try them out. Will they hurt my upper in the current configuration?

Do I need to regulate down the gas, or does it matter?
