they can't keep it, if they don't own it. They can rebarrel, replace, rebuild. But if you opt out of having them do one of the above, they HAVE to return it. It is Rugers policy to not have an overpressured, or any firearm that may be dangerous, returned. They will first try to get you to take an option other than sending it back, which involves YOU paying. Stand firm enough and they will replace or return it. But in the mean time, they will string you out for months hoping you cave in, and agree to pay what they ask......
