Nikon Buckmasters 6x18x40 mil dot or Bushnell Banner 6-24x40 mil dot
I have both of these. The Nikon has better glass, side focus, repeatable turrets, a more forgiving eye box, greater eye relief through the magnification range and comes with a 4 inch sun shade and a separate set of target turrets for around $320. I have had the Nikon on my .308 for a year + with no issues. The Bushnell Banner is a no frills scope with good glass, adjustable objective and good repeatable turrets (a little "mushy" though) for around $175. I have had one on my 30.06 for at least 3 years with no issues. I shoot both scopes to 500 yards every couple of weeks.
