Hello, I have a Springfield lightweight champion operator that I would like to get parts for but for some reason can't find a website that sell these parts. It comes with a "snap" takedown piece that you must put over the exposed portion of the guide rod between inner spring and the guide rod cap. To take it down for cleaning. This is a very small piece and would hate to lose it. I would like to find this "snap" half moon piece of plastic. Plus an extra guide rod and inner spring. Any help would be greatly appreciated. Thank you.
