I know this don’t answer your question, but I Never liked red dots. I am a firm believer in the K.I.S.S. Principle (Keep It Simple Stupid). I got enough to worry about trying to get a Tom into range w/o worrying my batteries might die in my scope. Not to mention decreased FOV especially on a moving bird.
I have shot open sights for over thirty years and never had an issue. And the fiber optics are very bright even in the woods at first light.
I have the TRUGLO Tru-Bead Turkey Universal Shotgun Sight on my turkey guns
So, unless you have vision issues, give this option some consideration
