Somebody here needs to disect a few scopes and figure out exactly where the problem lies. Is it a design issue or materials or faulty assembly that's at he root of the problem ? Until that happens, you're all just guessing and pissing in the wind. I don't have the bux to be tearing apart my scopes so It'l have to be left to one of you world travellers with deep pockets. As I said before, it's likely many if not most of the scopes from the majority of the manufacturers are using basically the same design. From there it comes down to materials and workmanship. Perhaps a change in the basic design is needed across the board. Simmons tried that with it's "flex erector" system a few years ago but it hasn't received wide acclaim so maybe more work is needed.
