Sometimes the sun can create artifacts that could be confused with a 2MOA dot. It's less of a problem on a rifle because it's easier to line up with a cheekweld, but it's still a potential problem.
I'm not sure this is a problem with the 407k, but based on reading different threads, it seems a problem that many sights are prone to. Somebody mentioned this issue specifically with one of the larger Holosun pistol sights. My theory is that a more complex reticle will be less prone to being confused with a sun-induced visual artifact.
I've been meaning to test this in low light with bright flashlights and car headlights, but I keep forgetting to. Just food for thought.
