So my boss gave me an old Remingtion Model 121 to clean up, but I now have a problem. I have put it back together and the bolt will not fit snug when you "cock" it. The teeth that interlock with the bolt and the upper receiver are sliding out from one another. I don't know if it was this way before I took it apart. Any suggestions, would a new bolt work? Here is a pic of what I am talking about see how its not fitting right?
