I recently bought Remington Genesis, when it came to sighting in with the factory iron/fiber optic sights...
1st 3 shots 8"low 50 yards.... move rear ramp sight forward & up....
2nd 3 shots 6" low 50 yards... move rear ramp sight ALL the way forward & up
Next 3 shots 5" low at 50 yards...
I can't move the rear sight any higher to adjust for shooting low. I want to have 1 muzzy with iron sights for Wisconsins
Muzzy season ( no Scopes )
I was shooting a 240 grain Hornady/Sabot with 2-50 grain 777 pellets

Do I need some kind of spacer under the rear sight???
No matter who shot the gun it consitently shot low.
Any help would be greatly appreciated!!!
