What does CT consider pre-ban on the AR receiver?
Has to have some sort of letter from the manufacturer stating the serial # and date of pre-94 manufacture as proof of being a Pre-Ban.
Some dealers won't import/transfer anything Colt or Bushmaster but the state police acknowledged them as being legal (Has to do with the previous AWB and models banned there).
Hence why it's impossible to get a Norinco AK because all the importers are
long gone.
Also the soccermoms united and save-our-children-groups are trying to get the pre-ban provision of the law closed up in exchange for allowing the 90% of people who didn't register their assault weapons a second chance to do so. So if you want a pre-ban you have a closing window.
Tough times ahead, friend.
