I have an auto cocker and I used it last summer ... worked fine. I got it out and the bolt is JAMMED in there... no broken paint or anything like that... I've never had an issue with this.... I was able to pull it out with some vice gripes but it will not go back in the gun... very odd... almost like the bolt expanded?
Any suggestions... sorry... don't know anything about cockers.... I bought this from a friend that needed money ... he moved away years ago. Could the marker need to be rehoned?
