I use the regular bead sights on my rem. 870 and they work great.I supose a lighted dot would be nice at night,never used a shotgun at night.I am going to put a fiber optic on front sight.I use #2 and BB lead, 35 yards is as far as i shoot.any farther and I use the rifle.I wont pay for heavy shot but I am loading up some 4 buck to pattern at 40-50 yd.Read the thread above on shotgun patterning,It will tell you about all you will ever need to know on that subject.
