I just rebuild a 1955 Marlin 39A it came drilled and tapped for a scope but the one that was on it was blurry at 20 yards. So I bought a new 3 X 9 rimfire scope for it and mounted it today. Problem is its still blurry at 20 yards. I unscrewed the rear set ring and turn the rear objective lens all the way out and all the way in but I still can not get it to come in clear. All my other scope have paralax adjustments on the front objective lens so it easy to get them clear at almost any range. Any help would be greatly appreciated.
