1981 Remington ejector stuck in . In the past I would soak in kroil overnight and it would work its way out or tap the ejector with a brass punch get it working and remove the pin and spring and clean and reassemble and move on . I bought this one used and the gentleman told me he bought it new and test fired it and forgot to eject the shell. Several years later when he decided to do something with it , there it was stuck so back to the safe it went till now. I have soaked it in kroil and removed the pin but can't get the ejector to move . What now a little heat on the bolt ?
