You will need to give us more information. Sears used the Ranger name of their JC Higgins shotguns and rifles. We may be able to get you a range of years, but not a specific year- there are simply no records.
I would go to Gun parts Corp. and find your JC Higgins model and exploaded view of your firearm.Then find the part number you need.they will tell you if they have it in stock.If not you may get the info you need to find them out in the general public.
About $150, more or less. Not very expensive, very decent shotgun. It is a High Standard Flite King.
