For my competition rifles, on my AR uppers, I have one with the Leupold 1 1/2-5, the other with a Leupold Mk. IV 2 1/2-8. On my precision rifle I am using a Sightron 6-24LRMOA.
I am very satisfied with these.
They cost more than the FMs. More or less double. I was hoping that the FMs would be in the best bang for the buck category.
