Very nice piece of work. Consists of a 6” V-style saddle bolted to a 7” D-style plate. Black anodized satin finish, with some underlying machining marks visible on the V saddle. Likewise on the clear satin anodized finish of the two clamping bolts. Even when fully tightened the knobs clear the edge of the D-plate by 1/2” so it’s unlikely they will run into any interference with your mount’s saddle. A nice touch are the non-metallic washers between the clamping knobs and the moving portion of the V-saddle, so no metal to metal contact to scuff and score. The saddle opens very wide, so there should be no issues there. But, if you are like me and like to open the saddle just enough to slide the scope in (so it doesn’t rock out before you get it tightened) you will appreciate the bevels of the V-saddle that slightly widen the opening on each end. Likewise, the dovetail on the D-plate is slightly narrowed on each end to make sliding it into your mount’s saddle a bit easier. Well done!
