Hi; could anyone please advise me on the best way to attach a red dot finder to the central mounting bar of my 20x90mm binos? I thought about double-sided tape but would prefer (if available) a more stable and lasting fixture such as a bar clamp with a dovetail plate for instance. I haven't found anything purpose-made online and searching at local hardware stores for bits and pieces has not been fruitful. Would be grateful for some ideas. Thanks.
