The Marlin 336 comes standard with a folding rear sight and a ramp front sight and there are several types of after market peep or ghost ring sights available to use with it. However, one thing that sets it apart from most other lever-action rifles is the fact that it has a solid top receiver and utilizes side ejection instead of ejecting spent cartridges from the top of the receiver. This is a rare feature on a .30-30 rifle.
For this reason, many hunters choose to mount a scope on their Marlin 336 rifle. Realizing this, Marlin builds the rifle with a reversible hammer spur to aid with the use of a scope.
