From what I've read at the NRA-ILA site which lists the codes, the letter of the law says that any copy of a Colt AR-15 not legally possessed before 9/94 is illegal . . .
That said every dealer I have spoken to says that the law is / was enforced the same as the federal ban so new, post ban compliant rifles are legal, and that they can and have sold many new manufacture / builds (post ban compliant) since 9/94.
They are reluctant to sell only a receiver as they dont know how yo are going to build it (and they dont make as much $$$)
The only question I have is how some new DA, liberal judge, or politician will interpret the law now that the federal ban has sunset and they dont have the BATF interpreting the law.
If anyone has any official statement from the NY Dept of Justice or whatever it is on this I'd be glad to hear it.
