Fellas, now I know that your going to tell me to call CVA, but. I have a CVA Optima and love it. Ordered on for my 14 year old son and when it came in, it seems to have a metal ram rod. Is this what it is, the one on my other Optima seems to be fiberglass. Not to sure about the metal ram rod on the crown. Your thoughts please. Also, what is the purpose of the threaded end on the rod that goes through the end of the breach plug remover socket. Thanks!!
