an AR in NY has to have pinned stock, pinned muzzle device and no bayonet lug unless its pre '94.
if its pre ban, you probly have to have it documented that its pre ban.< but this is just a guess.
all firearms have to be sent to an ffl
call a FFL in NY and ask, they should be able to tell you.
I have been a silent witness
to all of America's finest hours.
But my finest hour comes
when I am torn into strips and used as bandages
for my wounded comrades on the battlefield,
When I fly at half-mast to honor my soldiers,
Or when I lie in the trembling arms
of a grieving mother
at the graveside of her fallen son.
