Sig romeo 5x - SIG SAUER ROMEO5 1x20mm 2 MOA Red Dot Sight

After many weeks of searching the web, visiting gun shows and trips to retailers, I settled on the Sig Romeo 5X. I chose the red dot sight over other leading manufacturers of red dot sights for one main reason. Clarity. This was the only red dot sight in this price range that I did not see a red halo around the inside parameter of the sight tube. Not exactly sure what causes this annoyance, but when I'm focused on the red dot sight, I don't want to see a red halo floating in my sight picture. With the Rome 5X I got none of that. I also appreciate the fact that Sig switched the Rome 5X to a standard AAA battery. Replacing the battery is simply accomplished by removing a cap at the front of the sight. After installing this sight on my AR Platform, I co-witnessed with my buis and was zeroed in after several rounds. Hundreds of rounds later this sight is still performing to my expectations. Oh, did I mention how little it weighs?
