You could tear it down and head in to your best local hardware store. Stripped down it's just a metal rod. Or go to the link below. we use Numrich gun parts for schematics all the time. I was just having fun with ya! I have a model 60 with an after market stock and a little 4x scope on it. Had since I was 14. That rifle killed more jackrabbits on the Colorado prairie than I can remember! Oh don't forget the thread locker, as I recall mine would come loose also.I have a Marlin 60, with NO front sight assy. Could someone please tell me what thread the screw which threads into the barrell is? Your help will be appreciated.
