My buddy bought one for his ar-10. And I was comparing it to my vortex viper pst and vortex strike fire 1-6 and my primary arms 1-6. The glass was definitely almost as good as the pst but there was a huge difference in parallax between the two. Now his athlon was 6-24 and my pst 3-16. But I just hated his athlon at 24x, it was most usable for me at around 18-20. I can use my vortex at 16 all day long and not have issues. It was better than the budget SFP 1-6’s by a long shot. The glass wasn’t as clear as the pst but it definitely impressed me for what it cost. I wouldn’t hesitate to buy one for the price. That FFP sure makes a difference in ranging and at 5x, it was great with great vision on all edges. I think the problems are in the higher power level. You can sit there all day though at 18x and not get tired on the athlon.
This is what he bought:
