M1 7 round tube value?

[Vandal996]

I just sold my M1 to buy a M2. I was planning to buy a new M2 but at the last minute I found a slightly used M2 that came with the long mag tube so now I have two. I have a friend who wants it but I do not know what they are worth. It is the tube, Nut, spring, end cap and sling mount. This tube allows 7 rounds in the tube, one ghost loaded and one in the pipe and is pretty much flush with the end of the 18.5" barell to reduce any confusion about length. It is factory Benelli.

Thanks for your help.

Aftermarket tubes sell for between $50 and $80 dollars, a factory tube might be worth a little more. I guess the real question is, how good a friend is he?
