Hello! I am looking for a good set of sights for my Mossberg500. I'm using the stock bead at the moment. Originally I wanted a ghost ring sighting system but after realizing the sight it self is almost $100 then another $100 for a gunsmith to silver solder it on there... I even considered buying the Mossberg 590A1 barrel that comes installed with the front ghost ring, but soon realized that was pretty hard to come by. So I am looking for a set of rifle sights or fibre optic that install on a mossberg 500. I have found a few here in there on impactguns and brownells, but I would like some of your opinions. Preferably a set of dights that does not require major gun smithing.
