I have a Mossberg 590. It came equipped with ghost ring sights. I would like to replace the front blade with a good fiber optic/tritium/combination of both sight. Cant really find anything specifically for it tho.
That’s the only one I’m finding. Looked at Trijicon, XS, Dawson, HiViz, Night Fision, Ameriglo, Truglo, 10-8…nothing else specific to dovetail shotgun sights.
There are some dovetail rifle and rimfire front sights that you might look into. HiViz has some. Your existing sight looks to be 3/8" dovetail with .450" height. I could be wrong on that, best to verify with calipers.
