Can someone explain to me how you size your scope ends to the Butler Creek caps? I have one scope that came with those covers and they fit that scope well, but I haven't been able to size them adequately for other scopes.
I have a couple of scopes without covers and this thread got me on Amazon looking at the various brands you all have mentioned, Butler Creek, Monstrum etc. I stumbled across this brand of flip-up style and ended up ordering some for the scopes. Much cheaper than Arken's offering and they fold flat against the scope when opened.
We'll see how they hold up with the funky hinge design. I measured my ocular and objective diameters and rounded up to the nearest mm in sizes offered. All fit snuggly once adjusted with the included shim tape.
