T/C would fix it but.... I am not sure how the Omega stud goes in, but the stud came off my Encore. I bought the stud with the machine screw end for a $1 at the gunstore. Drilled the hole through the forend and counterbored the inside of the forend with a forstner bit. Installed the stud with a nut and lockwasher and some locktite. I assume an Omega could be fixed like this also.
If you send it back you are going to get something back that has the same method of installation, and as others have also said, it does not work real good. Mine broke when I was pulling the gun into a treestand, luckily the gun was only about a foot off the ground (I do not tie my rope to the sling anymore just in case).
