The cost of ammo is pushing me to get a .22 for fun/practice. I'm pretty sure I want a Marlin model 39, but I'm not sure what's best to look for. Are the current production models as high of quality as in the past? Is there a "golden period" in the used market (like with the Winchester Model70)? What about the different barrel lengths? Finally, if new is not the best route to go, then are there any rifle specific things to look for in purchasing a used model? Any thoughts are appreciated.
