WTB/WTT for Cheap used barrel for project gun

[GearShanty]

I am looking for a barrel for a single shot pistol project. Anything from .22lr up to 12ga. It just needs to be cheap, have a decent chamber and a few inches of good bore. A factory 10/22 barrel would work fine.
Let me know what you have.
I can buy or trade.

Thanks,
Bill

I have several, what is "Cheap" to you?

[GearShanty]

The definition of cheap depends on the barrel, but basically somewhere between $0 and $20. This is not a pressing project, so I'm in no hurry. Just trying to test the waters and see what's out there.

Thanks.
