Better with the circle - SIG SAUER Romeo 5 XDR Gen II 1x20mm 2 MOA Red Dot Sight

I have really enjoyed my Romeo 5 on my AR15. Easy to install, great aperture and I thought the red dot was the way to go simple and accurate. I was wrong. This Romeo 5 has all of that and the circle draws my eye to the red dot. It has made picking up the dot effortless. Optics continue to be excellent rain or shine, snow or heat. The only reason I give it a 4 is I am nervous about using a AAA battery in it.
