Most of the features of all the CT laws are unenforcable, except by either accident or house-to-house unannounced searches. I live there too, and I recommend to everyone that we don't comply, at all. Am I suggesting anyone disobey the law? Of course not - its an individual choice and could be expensive. But if you want to consider options, I'll list a few:
Civil disobedience is an honorable American tradition. Don't register squat, don't surrender anything. Make them come find you, and me, and everybody else. Jailing us all will bankrupt the state as fast as they jail us - not only the cost of housing and prosecutions, and support payments to families with no incomes as a result, but all the work that just won't happen while we're in the can.
Sure, they can make sure we can't order a 30-rd mag for your .22 online, but they can't stop us from buying a boxload of them out of state in person if they're legal in that state. Same with an AR-15. Buy at a gunshow, for cash, or from a private owner. If they don't know you have one, they can't insist you file any kind of transfer papers, can they? Just be careful to not be the guy who gets set up by an undercover agent (or some rat trying to avoid a prison sentence for trafficking women or drugs) so they can make an example of you. They will try that to frighten us into submission. Got one already and afraid of 'confiscation' or prosecution for not registering? Bury it off your property somewhere - directions for burial and suggestions for locations are available free on the internet. If asked, you sold it before the new law passed when the state didn't require any transfer record.
Last, you can 'vote with your feet' and leave the state. It might be hard to find a new job these days, but it won't be hard to find a state with lower costs of living and a more Constitution friendly legislature. I have a friend who keeps trying to sell me on Texas, and he just got a lot harder to refuse.
