I need a little help. Im looking at a Nikon Monarch 3 5-20x42 or a Vortex Viper 6.5-20x44. I have looked through the Vortex Viper, nice clear scope. My question is how does the Nikon Monarch 3 compare to the Vortex Viper ?? None of my stores around here have any in stock for me to look through. They are both around the same money. The Nikon has better eye relief than the Vortex , but the Vortex has wider field of view than the Nikon. Nikon is 1" tube, Vortex is 30mm tube. Trying to stay around $500 range . Decent used ones , like new in the box ones out there for $450 range. Strictly going on a hunting rifle. Thanks for any info.
