CT AWB Class 3

Ok so a few questions, forgive me I'm still new to here. Just registered my new assault weapon AR style so since its now registered can I add a suppressor to it, already has surefire break pinned on. And while on topic here what about all the other features that we couldn't have before since it registered can we breakout the collapsible stocks that everyone has been dying to get for years. Any information would help out.

Thanks I just gave them a call. So it looks like the majority of people are saying once its registered you can do what you want to do but the state hasn't given any answers as to the legality yet. Really no clear answers gray area.
