So I don't think I've ever noticed this happening with Teflon AR (which is what we tend to use), but we've tried a couple Zeiss Purecoat lenses at the urging of our rep. Basically what happens is this, we heat the frame up to make an adjustment, or to insert, or remove a lens and the lens coating crazes, or something like it. I feel like the coating is much more susceptible to heat than other AR's I've delt with. I'm wondering if anyone else has noticed this, or is my mind going? (I have been told I've been "twitching" lately....)
