rfrankhauser,
I doubt you will be able to do what you want. Most normal (Suhler einhakmontage)claw mounts have some kind of opening that people assume is to allow using fixed sights.However, in my admittedly short time(9 years)hunting in Germany, I never saw them used like this.The openings are,instead,intended to save weight.I did observe one of my hunting friends always walk to and from the stand, with his scope detatched ( he shot more than one Roe deer like this).
