I mounted a Vortex Venom red dot on my Mark IV Hunter. The group is 4 inches low at 25 yards and I am out of adjustment. What can be done to fix the problem?

Look around for a 10 or 15 MOA base. Might need to consult with someone who makes custom Ruger Mark pistol bases, but it can be done, and you will end up with plenty of adjustment.
Or, you might want to make a shim for under your base.

I used a piece of brass shem material insert the rear of the sight and it fixed the problem.
