I need to replace the on my .30-06 with something more like 4-16. The Steiner on my AR is a great scope but it's got a couple of problems. 1st, it doesn't have a turret option and changing the zero is a challenge. 2nd, my eyes are old and shooting out to 300 yards, 10x just isn't enough anymore. I can't afford a new Leupold or Vortex. Any suggestions are appreciated.
