What pistol are you using... Some you have to use the Visible dots to line up with equil light and equil light. Glocks you take the front and read sight and make the tops flush. Once thats done make sure there is equil spacing between the front sight and the left and right sides of the rear sight. I garentee you will be in black. I teach pistol marksmanship and shoot 50 yards constantly. Ill post a thred where you can see my shotgroups. My family is in Cali, Rocklin/ lincon area. We should hook up what im able to come home from GA and do some shooting.
