dont mind them at all.people complain about mounting height on a 50mm but i'd be willing to bet that most of your 40mm scopes have more than 5mm clearance between the bell and the barrel. you hardly ever see a 40mm mounted really close to the barrel.
i really like a 42-44m scope.
Not all of them. I like to get them down a close as possible.
