Any jag will screw into the silver end of that. If you want to extend your ramrod for easier cleaning and it has one female end, then you take the silver end off and that black handle will screw into the ramrod and make it a range rod. Midsouth Shooters Supply have them for under $5.00 . I have a couple of them in my range bag because I can make a second range rod for swabbing...
