Ok, this may be an amature question here. I have a couple H&R/NEF shotguns that are fairly old now. I have always wondered about swapping the barrels to rifle barrels and such. Here are a few things I have always heard but never checked into. 1) You cant go from shotgun to rifle with the older guns. Only shotgun to shotgun. 2) There are two differnt models (one older, the other newer) and its only the newer ones that the barrels can be switched on. 3) The only way to switch barrels is to send it off to the factory and have them change it and the I will be able to do it myself after that. But, it must be done that way every time you get another barrel. Now, how much of all of this is true? I know very well how uninformed people like to give well informed information. Can I swap barrels? How can I tell if I can switch barrels? And of course what do I have to do to switch barrels? Please educate me fellas.
