WTB: long barrel (at least 28") for Mossberg500

[Cos]

Looking for long barrel for Mossberg500. Desirable length is at least 28".
PTP in SF Bay Area.

I have a spare 28" one.
I think It's a modified choke with front gold bead
It's never been used but I think there's some slight surface rust
I work in the East Bay. You can look at it and make me an offer.
Got any trades?

I have a 28", 12 ga, 3" chamber factory vent rib barrel with accu-choke (screw in choke).

Good condition, comes with 1 choke tube - $85, shipped Priority Mail.
