I have an old Marlin 336 with a 3-9X Redfield Tracker scope on it. I inherited this rifle from my stepfather. The scope is blurry around the edges and I'm looking to replace it, even though it is still servicable, as evidenced by the javelina I killed at 90 yards a couple of weeks ago. I will probably go with some sort of 1.5-5X scope like I had on my original Marlin in 1973.
