I'm looking at getting some new caps for my Steiner P4Xi, 4-16x56. I have used Butler Creek for a long time but don't like them much, because they are too flimsy and won't fold down completely. I am aware of Tenebraex's covers, but they don't seem to carry one for the P4Xi (at least according to their search tool on the website, but I'm waiting to hear back from them through email). Suggestions? Thanks in advance.
