I just bought the 1.5 - 4X Leupold AR scope and I am wondering the same thing. I've always keep my scoped 'naked' and never had a problem. I've bought cheap plastic flip up covers (I think they were Butler Creeks) and they just break after like me blowing on it, so I've just kept them uncovered. I know, if I go into the jungle and through mud bogs, I will need a cover, but of all the hunting I've done, never needed a cover. Sure, I'd like to have a cover, but I'm like you, I ain't paying $65. I guess they are aluminum, which I guess is worth it, compared to the plastic ones.
