I just became aware of CT law from this thread.
Mass has more grey area about ARs.
I wonder if you could build or buy a CT compliant AR?
Is there such a thing?
Maybe requires some sort of bolt action or permanent magazine?
Maybe a wierd looking stock without a protruding grip.
NY and CA have odd restrictions like that.
The nuts and bolts of CT assault weapon laws as I understand them, and DCMDON and JAD may jump in here and correct me.
What I'm writing is based upon my personal experience, which comes from living in CT from 1977 until 2016 as a resident, and now spending summers in CT while living in Georgia.
Up until Sandy Hook, no big deal, buy what you like, and just do the 4473.
Post Sandy Hook, you had a limited period of time during which you could declare to the state any "assault weapon" you possessed and receive a certificate of registration for it. You also could declare your "high-capacity" magazines. (This of course is somewhat problematical because they're not serial numbered - but it means that you can legally have in your possession the items that you declared).
At that time, and the last I knew, you could still purchase "pre-ban" AR's, IE, pre Clinton ban. I have heard that this "loophole" has been closed, I do not know if that is true or false.
However, you cannot purchase, sell or transfer any non-pre-ban "assault weapon" in CT at this time with three exceptions -
1) There's a carveout for law enforcement and military; they're exempt.
2) You can sell your registered AR to a dealer to be sold out of state.
3) Your estate can transfer your registered AR to a successor upon your death, (providing they're "qualified").
I currently have several ARs that are registered in CT. I guard that paperwork very carefully. If any of those lowers are destroyed, I'm SOL, because they can't be replaced unless I can get the factory to re-issue the lower with the same serial number, which I doubt.
Many, many, many people in CT did NOT register their "assault weapons". Nothing has happened to them. However, it's an incidental charge if anything else goes wrong in their lives.
The only way you could could build a compliant AR would be to build one that doesn't meet the definition of an "assault weapon". So, I'm guessing a bolt-action would be the way. Which isn't really an "AR".
Connecticut sucks. But not as bad as Massachusetts.
And neither of them suck nearly as badly as California, New York, New Jersey or Maryland. They really suck.
