I hope that someone can help me with my question. I have both an ARESENAL SA M7A1 and an Arsenal USA SSR-85C-1. I shot both today and while cleaning both rifles I noticed that the bolt face on both rifles have pitting on them. There is a black ring that I can not clean off that is in a circle around the firing pin hole. The pitting is located on that black circle.
I like to rapid fire both rifles and I have recently been using the "Portuguese" green battle pack ammo. Although I do rapid fire both rifles, I am meticulous about cleaning and do so after every range session. The Sam 7 is less than a year old.
Has anyone else experienced this? Should I be concerned? Should the bolts be replaced? [/FONT] Thank you everyone for your help.
