Sounds interesting. I figured that the glue was permanent. I wasn't talking about the barrel simply moving on it's own I was referring to in 10-15 years after alot of shooting the difference that the barrel wear will have on the gun. Will the glue still release after that time? How about a refinish? Will the rust process of a reblue deteriorate the glue?

These were all things that I'd worry about with lining shotgun barrels with rifle tubes. Thus I found it easier to build up barrels sets by monoblock and rifle barrels.

Where are you putting it up for sale and what are you asking for the gun?
