Yes and no. If you buy from H&R1871 it must be fitted by them. If you buy a used barrel from someone else you take a chance if it might fit or not. If not, the chances are good you may be able to fit it yourself. On those rare occasions that it might not be able to be fit to one of your actions then just sell it to another forum member here. I would venture a guess that just about any barrel in decent shape could be sold here as long as a rerasonable price was asked for it and it were in decent shape. As long as one or the other of those conditions were met it would sell here. I have seen barrels that were described as not being in good shape that were priced a bit high that did not sell right away. That said, if the barrels were priced a bit lower, or were in a bit better shape and the shipping cost were only charged as the Post Office chaged them with no added markup anything should sell here, if for nothing else then for an experiment or spare barrel....<><.... :grin:
