As far as I am aware there are no restrictions on firearms such as the sks and mini14. From my understanding, they are not classified as an "assault weapon". Pretty much an AW in New York is....
A firearm able to accept a detachable magazine and one or more of the follow "military" features, collapse or folding stock, pistol grip, muzzlebreak/compensator/flashhider, ability to accept one of the previous meaning a threaded barrel, bayonet lug, a Grenade launcher, second grip held by non trigger hand. I believe that is all that is in the stupid law defining an assault weapon.
