I honestly didn't run any tests between these 2 scopes. I just happened to be sighting in a Rock River 308 with an Athlon 4.5-29x56 in for a friend of mine. He also has a Browning Hells Canyon with a NF 4-32x50 on it. I installed both scopes for him and just wanted to get him dialed in. I also have an NX8 on my Vudoo which I have been very happy with. I gotta say for the price the Athlon is one awesome scope. I felt that the Athlon was noticeably brighter and sharper then the NX8. I can't remember what he paid for it but it was around $1300 while the NF is around 1k more. Pretty sure both scopes are made in the same factory in Japan. Its gotten to the point were NF is pricing themselves out of the market. I'd love to get an Atacr 7-35 but they are over 3k. It pretty wild that so many companies are making pretty solid units for under $1500. Competition is helping drive the market. Anyone else has a chance to run them side by side? Too bad Shot was canceled curious if anything new will be hitting the market from these two companies.
