I started using Athlon Optics last year. The first one I bought was a 3x9 that I put on my 300 BLK for coyote hunting. I got this one, Athlon's Talos 4-16×40, for my 308. For the price, it is hard to beat--especially the clarity the optic. My first one has been through some abuse and has held zero well. While it is in the lower end of their lineup, it is still a good-quality optic.
