AFAIK, the new Steiner scopes are a totally new design, and are made in the Burris factory in Colorado. Steiner has been showing samples at the last two SHOT Shows. I had them in my hands there for a short while. The glare performance and aberrration correction were very good. It's hard to say anything else without having more time to test one.
Outdoor Life just reviewed one of the Predator Extreme scopes. Seemed like an editing hack job to me. I think OL's optics reviews have slipped during the last few years.
Beretta needs to step up their marketing. It's difficult to get any accurate or meaningful information about these scopes from the Steiner or Beretta websites. Even finding a company website that lists the scopes is a challenge.
Here's the only one I found:
Predator Xtreme Riflescope 3x-12x-56mm | Steiner -- The Binocular-Specialists
Vendor websites aren't any better.
