Yeah, I'm not sure what that is about. That's why I took a real up close picture. I didn't notice it or the slight coloring on the rear of the left side of the trigger guard when I picked up the rifle at purchase. The rest of it feels and looks like new.
That rear screw hole is disappointing, but not knowing Ti maybe it's an artifact of that metal? Either way, if I were looking for a .260 this rifle would be at or near the top of my list.
