Larry, welcome to this forum. Feel free to place a "wanted" ad in the "buy, sell, trade" section. Also, check Ebay daily. They have barrels for sale almost daily. I have had good luck adding a barrel to an existing gun. Some will just drop right in. On the ones that have required fitting, my gunsmith has had no problem fitting them. You may want to also get a separate forearm for the Hornet barrel. If the existing forearm is fitted to the Hornet barrel, then it may not fit properly to the existing barrel it was on. Just something to consider. Thanks for sharing your interests with us. Best wishes, Garnett
