Nightfarce? Ha!!! I missed that in your first post on my initial reading. Got quite the chuckle out'a me the second time around though. Something's amiss with NF quality control. Or as others have suggested - with your luck of the draw, you better stay away from Vegas. I've never had a scope fog on me in 35 years of use (knock on wood), but they've mostly been Leupolds (plus a couple Bushnells). Most recently I've converted to Zeiss and IOR. The Zeiss transmits more light than the Leupolds and has a little sharper resolution to my eye. The IORs have the best resolution of any of the scopes I've personally owned and used. I just pass my experiences along since it sounds like you're in the market for a non-Nightfarce. Good luck to ya...
