Do you ever really know what barrel you have if you did not see the blank or chamber it yourself? Is anyone really that confident in buying a used “Bartlein, Kreiger, or any other top tier” barrel for slightly less than what you could get a new one for direct from manufacturer most times? I am always amazed when I see used and already chambered barrels sell for top dollar, some people really do have a bunch of trust, good for them. I have purchased my fair share of used barrels, but never once did I expect it to be exactly what seller said it was, and never paid more than what I could get a cheap prefit for. (So far all my used purchases have shot well, not to say they are the same brand seller claimed though, or maybe they are?)
