Leupold made a change in diameter of ring posts which fit into quick release base. They now have two generations of parts, which will not cross mate. Leupod did not caution dealers or Optics Planet did not heed. I've been trying to get replacement parts for nearly a month and of errors in shipping and "in house" I've been frustrated again and again. No parts. What has happened to Leupold? Sad
Cons: Leupold Components -Ring to Base- do not fit together.
