I don't have a 336, but a Marlin 30AS (lesser quality than the 336). Mine as an older Glenfield 4x32 scope on it mounted on a low weaver base and it works great.
Mine has the cross bolt safety on it, which is a lot more reassuring. The trigger is a floating trigger (from what I've been told) so it won't fire and feels real flimsy when the lever isn't all the way closed.
