The Marlin 336 is a .30-30 lever action rifle that is the second best selling sporting rifle in American history, only behind the Winchester 1894. The 336 has sold millions since it was first introduced in the year 1948. Today, it is available in many different configurations and finishes and barrel lengths. The big selling point of the 336 over the 1894 is the fact that it has a side ejection feature on the side of the receiver. This means that shells eject right out of the side, rather than through the top on the Winchester, which allows you the option to add an optic such as a scope or a red dot if you so desire.
