At the range a few days ago was patterning my 590 and it was shooting about 12" low and 15yards :barf: Not to sure how to adjust these sights. Played with the spinner under the peep hole but maxed it out and didnt notice a difference, was holding steady with top of beed(or w.e you call these) center with the peep hole. No flinch or anything so i know its the gun. Any input is appreciated.
