Richard, First we don't use the S word here, it is part of the rules...Next to your question, if your gun has the molded polymer clad barrel the it is an integral part of the barrel and you will need to cut it off and then prep the end of the barrel to attach an LDC (Lead Dust Collector)....
We don't use the S word here? We screw a nut on and we unscrew it to take it off. Is the political correctness brigade trying to stop the world functioning completely? How ridiculously petty!
