Hi i have neen looking at the Athlon optics website and reading reviews from snipers hide everything i,read from the lower and up to the high end Conus line, got great reviews from tracking ,recticles light transmission and optics are super they only thing that would keep me from buying them is the lack of eye relief being in the neighborhood of 3.6-3.9 " .The first orginal diamond back (not the hp line)back had been criticized for only having 3.6" eye relief and i can tell you from personal experience my old Redfield 3x9 on my 300 weatherby and my sons 6x24 x50mm Osprey optics on his 300 RUM are at 3.6" and everyone has been bit and bloodied by that lack of eye relief. I say other than that what i have read the Athlon brand sounds great but i cant cut back on any more eye relief than what we have now .
