mueller optics does make a number of different scopes with an illuminated dot center. I thought about buying one, but I have RED DOTs on a couple rifles and a revolver, so there is no need to get one in a scope. Their price is not all that bad, but I have not heard any reports from actual users.

Now on a hunting show a couple weeks back this fellow in a cowboy hat was hunting elk. They showed the view through his scope and all his scope showed was a post with a lighted dot on the top of the pin. He made a really long shot on an elk with his rifle. Four hundred plus yards as I remember. He set that lighted dot and squeezed it off. He was out west, in the mountains, hunting with a guide in a snow storm on the last day of season. It was a pretty neat scope he had.
