look at the Form 4473 for There is no place that says lowers of any type are AW. Look at the Connecticut Forms also. Who Starts this stuff. What about Bolt Action Ar's you need a lower to start your build. What the law says is you cannot a have an AW under Connecticut law. An SBR is not an AW a Bolt action rifle is not an AW an AOW is not an AW under Connecticut law. Yes, you need to pay the 200 but now you are good to go for the SBR or the AOW. Bolt action does not require anything to own or build just use 10 round mags. Think of it this way you move to Connecticut with an AOW and you have your tax stamp. Do you have to turn it in to the police? Destroy it.. ? NO.. you can own it just as before. NFA items are legal in Ct.
