Evon, unfortunately the omni hybrid P4 5.56mm AR-15 pistol is not legal in Connecticut due to the magazine attaching outside of the pistol grip, threaded barrel, and manufactured weight of 50oz or more. Connecticut makes it extremely hard if not impossible to own an AR15 pistol, off the top of my head I can't think of any that would qualify as legal in Connecticut. You would have better chances with a AR style rifle but even that's slim pickings. Sorry but hope this helps.

Evon, unfortunately it is not legal as configured in Connecticut since it is a Semi-Auto with more than one of the following attributes : (1). Magazine that attaches outside
of the pistol grip (2). Threaded barrel (3). Manufactured weight of 50oz or more. Cheers and stay safe!
