Releasing a 56 mm scope as the first models didn't make sense to me
That's what a lot of guys said about the 3-9X40 Leupold in th early 1960's about the big 40mm lens. I don't see a problem with whatever works. Oblivious Nighrforce didn't make a mistake.
I thought that Leupold scope had a 42 mm objective. Then in the later 70's or so, it went to a 40mm, or I could be mistaken.
Just FYI
