Hi Folks. I am actually posting from the US. Not too many Sauer 202 owners here in the states so I hope some of you can help. As it stands today, my iron sight is already interfering with my scope view. I need to lower the scope rings down lower and doing so will surely have the iron sight blocking my view. I have decided to remove front and rear iron sights. Do you know the correct thread size for the plug screws to plug the holes?
