It looks like there is some kind of adapter screwed into the action and the barrel is screwed into that. There is an extra shoulder there. I would have given $250 for that. Did it come with the scope and mounts? I have a Kimber 96 Sporter in 6.5 Swede and it is a good gun but I could not get a Boyd trigger to work on it. It would not catch the cocking piece.
