Looks like built up crud. Dismount the bareled receiver from the stock and soak the area with solvent over a day or two. Then go get a 20 gauge shotgun brass brush, screw it into section of cleaning rod, and pour mineral spirits into a water glass. Chuck the section of rod into an electric drill. Dip the brush and stick it into the chamber, let her rip. There is absolutely no danger of damaging to chamber. Swish it in the glass and repeat until no more black crud washes off the brush. You will be amazed at the amount of stuff you will get from that chamber.
