manbearpig,
not to pig pile on. But I agree with underwhere. You sound confused.
The CT law simply considers the following to be an AW:
(A) A semiautomatic rifle that has an ability to accept a detachable magazine and has at least two of the following:
i. a folding or telescopic stock;
What is meant by telescoping and/or how quickly the stock needs to be able to change to differentiate between telescoping or folding and adjustable have never been clarified.
Truly adjustable competition stocks continue to be sold in CT.
So until it is clarified by a court, which requires someone to be arrested typically, we just operate under the law, as written with all its vagueness.
Even if one was to call the State Police, and get an opinion from them, it is just that, an opinion. It carries no weight of law. An interpretation from the AG office, while not carrying the weight of law, would at least serve as some protection if you were in compliance with their interpretation.
The practical aspect is that you want to comply with what a "reasonable man" would consider to be folding or telescoping. You makes your decisions and you live with the consequences.
I'd be comfortable with one allen bolt holding the stock in a set position as legal. But you make your own choices. Again, I have chosen to buy several pre-ban non-colt AR lowers, which allows me to (LEGALLY) put whatever I want on them as far as stocks, muzzle devices and/or bayonet lugs. I've actually got a registered SBR pre-ban lower that has a Zetta ZM300 upper. This upper has the mainspring over the bbl. So its an AR with a folding stock. Pretty cool. Very short.
