Hypothetically I don't see how anyone would know if the person's age adds up that they could have acquired it legally in that timeframe. Think about this....if say, someone's relative or parent gave them a legal unregistered firearm before the requirement to register it, or an inheritance, say pre 1980, and that receiving individual was of legal age to own a firearm, then they should be able to keep it unregistered. However, the verbiage in these proposed bans calls for all unregistered firearms to be registered. If that actually happens, it becomes a moot point and even your father would have to register it, unless of course he really never had an unregistered rifle and we are just talking hypothetically. I think if that scenario ever plays out, many people may take their chances and claim they don't process any unregistered rifles or cough up a token one or two just to give the appearance of compliance.

its just a lever action .22.  im not trying to circumvent any coming ban or whatever.  i was just curious, because sometimes, i go to the range without him, and i know you're allowed to let people borrow your guns, but if i ever got pulled over, i clearly am not old enough, and the check would not lead to any rifle in the database.
