The stock they are selling is made by Bell and Carlson, the stock in the video is a McMillian and was most likely shot before they contracted with BC for their new design.
I had a customer buy a stock from John and send it to me for a build, I really think it is a winner, it feels great, the forearm is not so wide that it will still handle well for freehand shooting. The grip angle as you can see is what we all like on prone guns. The price is reasonable, as well as the weight. I always skim bed the "aluminum blocked stocks" and have seen no difference in accuracy with a BC, HS, McMil, or Manners when all are properly pillar or skim coated.
