The Marlin Model 60 is the second bestselling rimfire semi-automatic rifle ever made, only after the Ruger 10/22. The Model 60 is also very soft shooting, accurate, and easy to shoot. It is available in both 14+1 and 17+1 configurations. The main difference between the 10/22 and the Model 60 is the fact that the rounds of the Model 60 feeds in a magazine tube underneath the barrel. Some people prefer this system, and it allows you to lie prone on the ground without having to worry about an extended magazine or anything.
