I just bought a Leupold MK4 LR/T 4.5-14x50. The lens on the objective side seem to have a bunch of little spots and a lenspen wont take them off. You cant see them when you look through the scope, but for $850 you would think the glass would be perfect. The little spots are not on the front part of the lenses. I usually clean my scopes with a little wet piece of toilet paper then get technical with the lenspen, but that wont take it off. The scope is brand new, I havne't taken it hunting or anything. I just hope its not defective.
