I have a lone eagle in 30-06. I've machined a new firing pin for it due to my dumb a$$ dry firing it to feel the break in the trigger. Seemed to work fine afterwards, BUT new issue. The whole rear breach has play in it when I have a round chambered and when I pull the trigger it just goes "click" instead of the usual muel kick to the arm. So I took it down and while doing so the whole assembly on the barrel unscrewed and looks like a bunch of rust and oil (possibly anti seize). So do I clean this off and put lock tight on this or is there another reason why this part came loose. Thanks in advance. Picture should show what I'm dealing with at the moment.
