I am not sure what I should be looking at but here are a couple of pictures. The barrel protrusion does not seem to be out of ordinary to me. I am beginning to believe that the cylinder may have other issues. It is nearly impossible to reinstall it without using something to compress the hand. I have tried all the tricks about hammer position and rolling it etc. I could find and it is still next to impossible. My other two Remingtons are not that way.
