Re: NXS or Mark 4?
Again, and I say again because people new to this forum always post, and others new to this forum always answer, without<span style="font-style: italic"> any </span>mention of what the rifle will be used for or what the person asking the question wants to achieve with the chosen setup.
Is the question: Which is the better scope brand, NF or Leupold?
Or: Which do <span style="font-style: italic">you </span>like better, NF or Leupold?
If so, then please spare the waste of bandwidth.
If not, then what, exactly, does the OP want to know?
Please, folks, can we agree that if you want to ask others about something it helps to at least show the common courtesy that you have thought the question through and are willing to articulate it in a way that helps other people give you the answers that you say you need.
