I may get flamed for this putting on flame suit but is there a rear ghost ring for the AR? I was looking for something for quick target picture for HD that did not rely on batteries. I know rear buis is the same but was looking more for something like this,
Almost all AR rear sights are peep sights, which are ghosted when you concentrate on the front sight.
Re: batteries, so many dot sights have great battery life, I can’t argue for sights that don’t use them, since these sights typically use Tritium that are much harder to replace after they get dim.
I have night sights on my handguns, but for rifles and carbines, Aimpoint, EOTech, or my beloved ACOGs
