This concerns the thin spacer piece that was provided with Buehler split scope rings. I'm aware that the rings were available in both 1 inch and 26 mm sizes. But, did both size rings come with the spacer piece as part of the assembly, or did the addition of the spacer make a 26 mm ring out of a 1 inch ring? In other words, what is the purpose of the spacer piece? (If this question is more applicable to the "Accessories" threads, I sincerely apologize.)
