I know this is an older post, but I'm wondering if you were ever able to find an extractor. I have the same problem with that model Remington. I've only found aftermarket parts that need fitting and I'm not sure I'm not sure I trust myself to do it. I'd appreciate any information that you may...
I used the certificate from the DNR Hunter Safety course to get mine. The paperwork is not that difficult and it comes with instructions. You can request all the information online.
