I sent the barrel for replating with the tube inserted, and received it with the tube removed, so I do not know how to remove it. I see that the tube is immaculate, no scratches, no rests of sealant/glue in the length that sits inside the barrel. The other portion is slightly corroded, so I assume that's where it is wet.

I'll cool the tube before inserting it with some loctite/epoxy all arround and check that it doesn't move when pulling by hand. Will report results.
