wow. So many comments.
I tell customers if you have only one scope you can buy, it should be the ATACR 1-8x. Truly remakable, and bullet proof. That said, up until this week, the Razor HD-II 1-6x has been hard to beat. Almost as good as the Nightforce, at 1/2 the price. Now, I do not think the Razor will withstand the beating of an ATACR, but the 1-6x Razor HD has proven itself to be a great value and a good optic, and much more consitent quality than the higher magnification Razors which have been hit or miss out of the box.
But, with the Razonr Gen-III priced just between the 1-6x and the ATACR, I think the Gen-III 1-10x will be one of the best selling scopes this year.
How do they compare? The 1-10x Gen III does very well. Optics are like shoes. Everyone feels a different fit. At a price point $800 or so below the ATACR, it will be hard to justify the extra money, unless your life depends upon it. Or, you just don;t need 10x.
I have had the same arguement with the execs at S&B about their 1-8x Dual CC. They argue it is the best engineered LPVO on the market. They, of course, are correct. Germans are great engineers. But at $k or more over the ATACR, do you really need two focal planes in an 8x scope. Engineering and efficiency are different. I still respect the S&B scope, but at what point do you say, "okay, this is good enough ?" The same is true, in my opinion of the ATACR v. Razor Gen-III. Quality, usefulness, versatility and durability: my vote goes to Nightforce. Great scope and great value, and the ability to zoom further: Vortex.
Personal preference.
