The glass and quality of the coatings are different as well. Plus the turrets and power of the BEAST is different... at SHOT Show they said they did a comparison with all the top brands like Swarovski, S & , etc... they all picked the BEAST... they were all anonymous, supposedly. It's a nice glass but pricey.
5-25×56 ATACR™ Riflescope
ATACR
What’s in a name? In this case, everything. Our all-new ATACR™—Advanced Tactical Riflescope—builds upon the long and successful history of our NXS™ series. The result is a riflescope of unprecedented long-range capability and image quality. The 34mm tube allows 120 MOA/34.9 Mils of elevation adjustment—20% more than our most capable NXS™. Fully multi-coated ED glass results in light transmission values of over 90%, brilliant images and exceptional color contrast. A magnification range of 5x to 25x, and a wider field of view as a result of its unique optical prescription (17.96 feet at 5x) will cover virtually any situation a shooter could encounter. All this power comes in a compact package, too, measuring just 14.3" in length. Our patented ZeroStop® is standard, and the ATACR™ is offered with two of our most sophisticated reticles, leaving nothing to chance. The ATACR™ redefines the "long" in long range for serious shooters and hunters, pushing the envelope of precision…and possiblity.
