    Clint has a sizing question series to get you rolling. Current port is irrelevant.

    Yes, if a new extractor spring doesn't bring it back to proper function, and it's still ejecting to 1:00, the next step would be to address gassing.

    An EZTUNE is a great fix if the gas port is eroded but the barrel is otherwise fine.
