In my opinion a Nikon will hold up to about anything that a Leupold can withstand. As for repair time, of the items that I have sent in for repair, they have returned back to me within 1-2 weeks, No Charge! That same as Leupold. The eye relief is 3.5", which is adequate for any rifle, but maybe not for the really big shooters. Plus the Nikon is $100.00 cheaper than the Leupold. A lot of people think that Leupold is the only scope! Don't get me wrong, Leupolds are nice scopes, but there are other brands out there that have just as good or better quality for a lot less. Another good example is the Bushnell Elite 4200's.
