What are these tubes for ?

28 ga tubes. There should be a slide hammer to go along with them. Drop into your 12 ga O/U or SxS some tapping with the slide hammer might be required, but I should stress tapping not pounding. Make sure you line up the ejectors with the one on your gun. You now have a 28 ga.

Many skeet shooters use tubes in a 12 gauge gun, to shoot the other gauges, it's much cheaper than buying extra barrels.

And they are worth a pretty penny.
