My gunsmith has a bit of a hard on for US Optics scopes these days. He is building .260s for 1000 yard shooting. He showed me one of his five rifles with the big US Optics scope on it with the big ranging wheel on top. I never read anything about them, but he sure likes them. I grew up with S&B, Swarovski, and Zeiss being the big three. Now, I hear that March scopes are the best available, and the competitive shooters who can afford them, have them. That and my gunsmith is favoring US Optics, which I never heard of before seeing his.
