I have some concerns about this as well. Nothing really shows the Zulus used on anything other than an air rifle. Most people express concerns over the eye relief as well. I only plan on using a 5.56 (for now), but its a concern for the future. Also, where's the rangefinder? Does the ballistic calculator function work, or available? I truly hope that Arken updates their website with some info, because I did purchase one, but I'm having second thoughts about it now. There are claims that it will handle most everything you throw at it, however that's all a mute point if you're in the ER getting your orbital socket stitched up.

Good to know, and once again you are spot on. They are extremely hard on optics.

Thank you PW for your response. You are the only one that understands exactly what I meant when I posed the question. I may wait a few to order mine and try it out. I don't get to the range as much as I used to.

They are pretty good about getting back within 24 hours is my experience.
