Al I know is that Mark builds very fine HUNTING rifles.
He built me a .270 Weatherby on a 700 action that started shooting extremely well right out of the gate--and only weighed 7-1/2 pounds with scope. Now, it is possible to make them lighter, but that was light enough for me in that chambering.
One other thing: I have owned and tested quite a few custom synthetic-stocked rifles, and Mark's was one of the very few that came exactly as I requested in every way, from the chamber to the trigger pull, and didn't need any tweaking.
