You can purchase and ship into state anything over 50 years old. exempt from transfer law but not registration I believe this answer was based on Subdivision 22 of section 265.000, chapter 189 of the laws of 2000, amended by the legislation/signed law. 22 (A) & (G) (VI) & (H) [any weapon defined in para (E) or (F) ... only transered outof state or to a dealer], basically exempts anything that is 50 years old from being classified as an assault weapon even with a detachable magazine but registration still required.
Another example of confusion and just my take on it and the phone conversation.
BTW I believe local visiting hours are Monday 1200-1500 and I prefer Winston but anything will do.
