So i took my rifle to the range and im trying to zero my iron sights. Well im getting good groups but at 50 yards im still hitting close to a foot and a half higher then where i am aiming. My front sight is adjusted almost to the point of falling out and i dont know what else to do. If i raise the front sight anymore it will literally fall out. im using a red dont this year for hunting but i would like to have my iron sights good to go just in case.
