I have a 500, 20" plain barrel (not ribbed) with the longer 7 round mag tube and configured for tactical. Any other owners of these 500 knows it's hard to find a good front sight that will work properly. I currently have a green laser rifle sight attached via a picatinny rail on receiver. I've looked at several front sights so I can remove laser and the only one that seems it will work is the XS Big Dot Titanium for the Mossberg 500. Has anyone put one of these on your 500 and if you have how is it working i.e. good during day light and night time use. Also is anyone using a tactical flashlight on your 500 and if you are which one and how is it attached.
