By the way, if you want to remove that sling "stud" (probably called something else ?) from the ramrod barrel (thimble), here's how. Spray that stud with your favorite penetrating oil. Grab your favorite gripping tools, and grip the barrel, protecting with a soft material. Find your favorite tool, that will slip through the hole of the stud, and turn the stud "lefty-loosey". Your "stud" will be removed from the barrel.
BUT... Dixon's will do all that. LOL
