The reason is our state Assembly and Senate are comprised of idiots.
New York is home to legislators who think a barrel shroud is "that shoulder thing that goes up" and therefore must be banned, that "heat-seeking bullets must be banned", and that frangible bullets must be banned because they're armor-piercing. Seriously. That's what we have to work with.
New York allows a maximum of two "evil" features which include a pistol grip, bayonet lug, removable magazine, collapsible stock, etc. An AR has a removable magazine and pistol grip, therefore the stock must not collapse, the bayonet lug must be ground off, the barrel either has to have nothing on the end (no threads) or have a muzzle break silver-soldered and pinned.
These are arbitrary, pointless laws that serve no purpose other than to make life difficult for New Yorkers.
