Thanks Billyvan. I can see what could be a shallow punch mark on the bolt, just forward of the extractor. This might be what David is talking about. I think I can also see a bomb on the right hand receiver rail, adjacent to the extractor. I have a question ? I'm going to post a pic of the scope block in the dovetail to show the guys what you described. Maybe get their advice on what to do about it ?. What I want to know, "Has anyone ever seen that line and mark above the Inland Div in this S/N range before ? ". I've been in Hospital for two days but am now back on the "front line", so let me know if you want me to post the rest of the pics. I know the ones the guys will want to see. Cheers Bud, Mike.
