At one time I had a Krieghoff made 16ga/22LR insert barrel. This barrel could be sighted in to the shotgun sights & had its own extractor. It was very accurate & could be removed & reinserted without losing Zero. It was also quite expensive, I don't know if they are made anymore. These were made primarily for use in drillings which of course had sights for the rifle barrel.
