If you are talking about Gunstocks, Inc. they are fine folks. The majority of the shaping is done, but you have to do final sanding and fit the barrel channel. I wrap sand paper around dowels the same diameter as the barrel, and sand the channel to the contour I want. I set in stainless steel pillars in the forend to allow me to float the barrel but I am not convinced that is necessary. Just something I do.
