I guess the good folks at Nightforce work a four-day week otherwise I'd know the reason why they discontinued the 3.5-15x50mm F1 scope that I bought from them about two years ago. It's a very good scope but my guess is that they didn't want to cannibalize sales of the 4-16x42mm ATACR F1 scope which appears to be the only scope like it ... based on their incredibly slow website. Any insights?
