Tapped holes in the top rib-Why? Did the rib come loose and have a cheap hacker type fix or possible scope mount? Looks like the stock was cut with an extension glued on. Someone got a decent shooter at a possibly decent price for what it is. Personally I wouldn't have even gave the gun a second look due to the issues I see with it. If the gun was in decent original condition it would probably bring slightly north of 10k.
