Maybe you should have actually read "None of the above" before posting. Post #2 and #3 for example. The manual hold open was the culprit in this case. Happens now and then when a Marlin 60 gets passed on to a new owner without the manual.
The "pin" you're referring to is the ejector/lifter spring
and it can be a pain in the a** if it the leg that serves as the ejector gets bent or knocked out of its groove on the feedthroat. This can lead to cycling issues, prevent the bolt from going into full battery, misfeeds and ejection issues.
Now I'm irritated. I tried everything and could not get it. Your suggestion worked !!! Thanks a million. !!!
