I have a GCNM manufactured in 86 (talked to colt rep)with the collet bushing.I read here somewhere that the 70s and early 80s series only had them.Could this be something the previous owner installed or did colt install them at least until 86? Ive had no problems with it ,just want to know for my own knowledge
