I have a set Warne Quick Detach/ Return to Zero Scope Mounts on my Remington 7400. They have given me good service. While reading the Brownells catalog I see Weaver and Leupold make them also. The Leupold is a solid base. Anyone have experience with the Weaver or Leupold mounts? I a mounting a Nikon 3X9 on a Remington 7600 in 35 Whelen. Any thoughts in general about Quick Detach/ Return to Zero Scope Mounts? Thanks, MIKE.
