The screw and sling loop are fine, it's just the ring of metal they're both attached to is broken.
** EDIT ** Upon further inspection, it is the whole assembly (barrel band) that needs to be replaced.
The good news is that the serial number is 115182 INLAND. This means it was produced in the first tenth of the first batch of M1 Carbines ever made by any manufacturer (excluding test/bench models)! Correct me if I'm wrong though.
