They were made between 1947 and 1965 or so, so the quality is wildky variable. I have been seeing them going for $ 50.00 to $ 165.00 in good condition. I just saw one being put up for bid online with a suggested starting price of $ 265.00, though I don't think they'll get it. Great shooting .22! Get one if you can. CPRWIZ

The Remington Model 760 was not chambered in .284 Winchester, so I am unsure what caliber you are referring to. sales@countrygunsmith.net
