Not a hard repair, it's separating at the seam I'm not sure how many piece the kimber stockmakers mold is, but guessing it's cracking down the line where the two halves come together. Betting dollars to donuts it was a lunch break bad prep kinda deal. A repair is going to require some grinding, bit of epoxy and a re dip.
I've been waiting to pickup a specific kimber for over a year now and have watched inventory pretty hawkish. It's been very few guns shipped with most being hunters (plastic stock mag fed) a little shot of mountain ascents and a few of the heavier open range line. My guess is for the last few years something has been up with the stock maker that makes the Adirondack and montana rifles. Guessing montana is all they have in inventory for repairs. If they had a steady stream of either we'd likely see Adirondack and montana rifles showing up on the market outside of used ones on gb.
