I don't think they are sold anymore, but I do have a pair of 12ga to .410. They are 12" long, 3 1/2" at the breech end is steel, 8 1/2" aluminum with an o-ring at the end.

I used them in an old Batavia Leader with considerable pitted twist bores and a few small dimple dents. It's bored ic/ic.

Anyone have an opinion on using them for twist steel barrels?
