My girlfriend got me this set of shotgun sights as a gift for my 590: AmeriGlow Mossberg 590 A1 Night Sight: Mounting Solutions Plus (MSP)
Unfortunately they don't fit because I don't have the A-1. It comes with sights already mounted and these are intended to replace them. Can I get the mounts that the A-1 comes with or do I just have to look for different sights?
I'm just looking for a solution to put a simple 3-dot tritium setup on my 590.
