Not a full-blown range report. Just a photo of my latest toy for the Ruger AR556. I'm happy with the Vortex Strikefire 2 I bought last month for my birthday. I mounted it and took it to the range last weekend. It performs as advertised. I'm relatively new to red/green dots and this arrangement works out well for me. I'm not much interested in co-witnessing, though this arrangement is advertised to be lower 1/3 co-witness. Personally, I just wanted to set the Vortex at 25 yards and leave my irons at 100yds. Sighting the irons through the tube is not a problem.
