14" "Tactical" super 90's with adjustable sights. Does anyone REALLY understand these? Two different gunsmiths have worked on two different weapons with poor results. Is the complicated (?) double screws and two washer/cams really not for adjustment from brand ammo to another brand ammo? Am told to set sight with selected slugs and locktite it and leave it alone. Now I am told the sight hits 2 inches high at 50 yards. I am taking it to my range after I get this out and seeing what the impact is at 10, 15, 25 etc. This is really frustrating.
