I have a Nikko Stirling Nighteater 6x24x44. That is what is on my 700 in my avitar pic. It took a little getting used to as far as eye relief goes but I have had it for a year or so and it is just fine. No problems. I have a female friend that likes to shoot and within 5 shots, I had her blasting small Gatorade bottles @ 300yds. As far as filtered light or dusk and dawn shooting, no problems. Clear and bright. If I were to buy one again, I would go with less magnification. Hope this helps.
