I recently bought and installed a gobble dot sight on my shotgun. In the package, the front and rear sights are close together and appear to be very bright. At home, after installing them, I have noticed that, although the rear sights remain bright, the front sight appears very small and not very bright. It disappears completely when aimed at a bright window (from inside). I was similarly disappointed with it's low-light capabilities. You need a good amount of light to see the sights at all. If one flies in from the roost, I may be in trouble with this sight.
