I also purchased a Gunsmither Barrel Block. Fortunately, no modification to the barrel was needed. The part of the barrel that would normally require filing was perfectly flat. Instead of pulling the barrel down and causing droop, the Gunsmither pushes and supports the barrel, and no more worries about over-torqueing the screws. According to my feeler gauge, there's a .004" gap between the dovetail and the Barrel Block, so I probably could have voided use of the set screw, but used it anyway.
