Ah, the $62 was for a single cannon 'system' vice a single cannon... that's what I get for looking at things when work was busy
Its not an upgrade charge at BC as you get the stainless barrel in addition to the regular copper one for $9.25. Im sure if you asked you could sub out the copper barrel for the stainless barrel and get a discount vice purchasing both.
It's just a play of words.... bottom line, at BC if you want stainless you pay $9.25.... He might knock of a quarter for the barrel if you ask...
