If any barrel is lose when the action is closed with the forend removed, it needs to go back to H&R for repair, likely for a new barrel which will be an extractor cuz that's all they make now. If it only wiggles with the action open with the forend on, it doesn't matter. If you want to repair it yourself, see my barrel fitting info in the FAQs, but if it's a factory fitted barrel, you should take advantage of their CS and call them to make arrangements to have it fixed, ask them to cover shipping too, toll free (866)776-9292.
