I just bought a Marlin 336C and mounted a scope on it. Not being suspicious enough of advertising claims, I first opted for a 3x-9x 50 mm scope on Weaver see-through mounts. Mistake. You could see the iron sights, alright, but not what you were aiming at. Backed off and switched to a 40 mm objective bell and standard medium Weaver mounts, and the situation was much improved. I'm still not happy, though. I like to get a good cheek weld when I shoot, and I can't do that, not quite. I hope I can do better. With the rear iron sight removed the objective bell of the scope is still 1/4-inch above the barrel, and the ocular bell is more than that above the hammer. Can anyone suggest a mounting system which will reduce that clearance?
