If you buy an old model 60 might want to invest in a new buffer
Quite true. It takes a beating.
I bought the Glenfield version back in the 80s, knowing that it was a cheap rifle. But, I bought it to see how well it would perform after extended shooting, and just for fun.
I also bought a brick of Winchester Super-X to put through it.
My impressions were that it was quite reliable and accurate and I liked the slender feel of it for offhand shooting.
After 200 rounds with no jams, I field stripped it at home to inspect it and to clean it.
I was disappointed to discover that Marlin had used a styrene plastic take-down pin to hold the lower action in place, and that this had broken at some point. But, it had still kept working.
I replaced that pin with a piece cut from a section of a cheap .30 caliber aluminum cleaning rod, solving that issue permanently.
After that I finished off the brick (300 rounds) and again experienced no jams that I can recall. It was very reliable.
However, when I field stripped it again I was annoyed to discover that the plastic recoil buffer had broken. Obviously, someone at Marlin had made changes to the original parts to save money and had not bothered to test their endurance before mass producing them.
So, I carved out a replacement buffer from a piece of rubber and installed that, solving that problem for many thousands of rounds.
Overall, it was a great rifle, and assuming that the pin and the buffer problems were corrected, it still is.
