Dane,
Many old marlins bought here in pawn shops and from old timers will have the Weaver see thru mounts on the rifles. Almost all are removed and replaced with low rings to place the scope as low as possible for a proper check weld on the butt stock.
The times have changed regarding scope mounting on Marlin 336's.
Your choice or the 2X-7X scope will allow you to mount the scope lower on the receiver than a 40 mm front scope objective.
