I've been looking at this optic for a few days and wonder if anyone here has an exp with it. It's a 3x30 ACOG with the green horseshoe reticle. I'm looking for a short range optic, point blank to 300 yards for 5.56. I need it light and compact. How well does the green show up in really bright light? How well does it show up in complete darkness? Is the green better/faster than the red or amber? I've heard these ACOGs are great at distance, but I'm not sure about close in use. How does it perform in the 50 yards and under range? I've looked at red dots such as the Comp M4, but I'm concerned with target identification/observation. Any thoughts or other options that would work better would be welcomed. Thanks.
