Thanks for the pics! it looks way better inside than my carbon kevlar stock did before I bedded it. If you're curious, here's the thread from the last person who made carbon kevlar stocks (besides McCann).
You might want to screen that thread to identify any potential hurdles you might overcome.
Hueygunner insisted that the stocks did not need to be bedded, but I still routed mine and bedded it a year ago. If anyone wants to bed your stocks, it can be a bear to work with the carbon fiber. Again, there WILL be differences in receiver geometry. The new Rock-Ola receivers have wider legs (from front to rear) and stock liners are having to be modified to get them to fit.
Other people will want heavier contours, like the heavy McMillan stocks as well as stocks with adjustable combs. Holes pre-drilled for rails and bipods will be a plus.
Also, can you include a pic of the inner forearm area? My stock was one of the CF stocks that Phil observed. Mine is either cracked at the pistol grip, or the stock flexes in that area and the paint chips. Either way, it's still a solid stock and I just shot my best groups with it; 20 rounds in 1.7", 5 rounds at 1.1".
