I'll throw my hat in the ring, but I may get a few giggles or two. For the better part of my life, I have spelled scope, L E U P O L D. Long story short, as of recent, I have added a few Nikon Monarchs to my collection of glass and iron. My Sharpshooter, wears a 6.5-20 UCC Monarch. It is crystal clear, even at high power, tracking is excellent, and if you could shoot as long as you can see through this scope, you would be WAY past LEGAL shooting time.
My Custom STW, wears a VARI X II, 6-18, target model. It worked wonderfully this past fall. I just added a 5-20 Nikon Monarch to my 308 VSSF last week, and I am very impressed with it as well. I personally have faith in two above scopes, and must admit that li have a soft spot for a Vortex Viper, like my Bro' Gamehawker uses.
The Nightforce scopes are probably the best scope ,except US optics, but both of them are a little out of my reach.
