Ok here is the deal. I have this New England 20 gauge single shot. I have had for years. It was my very first gun to own. Well I remembered that when I bought the gun it had a paper that said I could buy different types of barrels for it like a 12 guage barrel or just about any other shotgun. Does anyone know where I can buy another barrel for it?

hr1871.com. That is the NEF-H&R site. Click on barrel accessory program. You may have to call their CS department and give them the Serial number before they can tell you for sure what barrels you can get. They are pretty cheap to buy. You will have to send them the reciever to fit the new barrels.
