Wow, there's a lot of bad information in this thread. Let me see if I can clear this up a little.
First, don't bother with the list in the link above, or the links that site contains. If you really want to know what the law says, here's a link to the actual language.
http://open.nysenate.gov/legislation/bill/S2230-2013
Of note is the fact that all "Assault Weapons" must be registered within one year, and may not be transferred to another person residing in New York State, and that "High Capacity Ammunition Feeding Devices" may not be possessed, and may not be transferred to another person residing in New York State. Here's the definitions for those terms. Note that I <snipped> and {paraphrased} some of the extraneous information to make it somewhat easier to read. Also note that there's a list of exceptions at the end of each quote.
By New York State definition, "Assault Weapon" means:
A SEMIAUTOMATIC RIFLE THAT HAS AN ABILITY TO ACCEPT A DETACHABLE MAGAZINE AND HAS AT LEAST ONE OF THE FOLLOWING CHARACTERISTICS:
A FOLDING OR TELESCOPING STOCK; A PISTOL GRIP <snip>; A THUMBHOLE STOCK; A SECOND HANDGRIP <snip>; A BAYONET MOUNT; A FLASH SUPPRESSOR, MUZZLE BREAK, MUZZLE COMPENSATOR, OR THREADED BARREL <snip>; A GRENADE LAUNCHER
OR
A SEMIAUTOMATIC SHOTGUN THAT HAS AT LEAST ONE OF THE FOLLOWING CHARACTERISTICS:
A FOLDING OR TELESCOPING STOCK; A THUMBHOLE STOCK; A SECOND HANDGRIP OR A PROTRUDING GRIP THAT CAN BE HELD BY THE NON-TRIGGER HAND;<snip>; A FIXED MAGAZINE CAPACITY IN EXCESS OF SEVEN ROUNDS; AN ABILITY TO ACCEPT A DETACHABLE MAGAZINE
OR
A SEMIAUTOMATIC PISTOL THAT HAS AN ABILITY TO ACCEPT A DETACHABLE MAGAZINE AND HAS AT LEAST ONE OF THE FOLLOWING CHARACTERISTICS:
A FOLDING OR TELESCOPING STOCK; A THUMBHOLE STOCK; A SECOND HANDGRIP <snip>; CAPACITY TO ACCEPT AN AMMUNITION MAGAZINE THAT ATTACHES TO THE PISTOL OUTSIDE OF THE PISTOL GRIP; A THREADED BARREL <snip>; A SHROUD THAT IS ATTACHED TO, OR PARTIALLY OR COMPLETELY ENCIRCLES, THE BARREL <snip>; A MANUFACTURED WEIGHT OF FIFTY OUNCES OR MORE WHEN THE PISTOL IS UNLOADED
OR
A SEMIAUTOMATIC VERSION OF AN AUTOMATIC RIFLE, SHOTGUN OR FIREARM
OR
A REVOLVING CYLINDER SHOTGUN
OR
A SEMIAUTOMATIC RIFLE, A SEMIAUTOMATIC SHOTGUN OR A SEMIAUTOMATIC PISTOL OR WEAPON DEFINED {in the 1994 AWB}
BUT DOES NOT INCLUDE ANY RIFLE, SHOTGUN OR PISTOL THAT IS:
MANUALLY OPERATED BY BOLT, PUMP, LEVER OR SLIDE ACTION; OR HAS BEEN RENDERED PERMANENTLY INOPERABLE; OR IS AN ANTIQUE FIREARM <snip>; A SEMIAUTOMATIC RIFLE THAT CANNOT ACCEPT A DETACHABLE MAGAZINE THAT HOLDS MORE THAN FIVE ROUNDS OF AMMUNITION; A SEMIAUTOMATIC SHOTGUN THAT CANNOT HOLD MORE THAN FIVE ROUNDS OF AMMUNITION IN A FIXED OR DETACHABLE MAGAZINE; OR A RIFLE, SHOTGUN OR PISTOL, OR A REPLICA OR A DUPLICATE THEREOF, SPECIFIED IN APPENDIX A TO 18 U.S.C. 922; OR ANY FIREARM, RIFLE, OR SHOTGUN THAT WAS MANUFACTURED AT LEAST FIFTY YEARS PRIOR TO THE CURRENT DATE
And, also by New York State definition, "Large capacity ammunition feeding device" means:
a magazine, belt, drum, feed strip, or similar device, that has a capacity <snip> to accept, more than ten rounds of ammunition, OR CONTAINS MORE THAN SEVEN ROUNDS OF AMMUNITION, OR IS OBTAINED AFTER THE EFFECTIVE DATE OF {this law} AND HAS A CAPACITY OF, <snip> MORE THAN SEVEN ROUNDS OF AMMUNITION
[The above] does not include an attached tubular device designed to accept, and capable of operating only with, .22 caliber rimfire ammunition OR A FEEDING DEVICE THAT IS A CURIO OR RELIC.
So, here are some quick observations ...
I think, if I put the wooden stock back on my Mini-14, instead of the folding stock, it would be legal, as would my Ruger factory 5-round magazine. But, my Remington R-15 VTR would be banned, even though it also came with a 5-round magazine from the factory, simply because there is no option to change out its pistol grip.
There are absolutely no references to revolvers, except shotguns with revolving cylinders.
There is a specific exemption for tube fed .22's, but no such exemption for other .22's. So, my Winchester 190 is OK, but the 10-22 may not be, depending on how it qualifies under the "one-feature" rule (target stock with a thumbhole grip? nope... banned).
Another interesting bit... the Desert Eagle is banned, due solely to it's weight (over 50 ounces is banned; the DE weighs about 70 oz.).
And, of particular interest... There is no differentiation between magazines for rifles and pistols. So, while most .45's will be OK due to their 7-round capacity, the vast majority of 9mm pistols are now effectively banned, because there are - to my knowledge - no 7-round magazines for most 9mm pistols. Likewise, many .22 pistols are effectively banned for the same reason.
Yeah... all this passed each house in less than a day (introduced on the 14th, signed into law on the 15th), with no public input, and no debate. Heck, I doubt anybody even had time to read it.
So, I wonder... can somebody that gets arrested for violation of this law claim that their rights have been violated because there was no due process granted when the law was passed?
I must say, I feel bad for the people of NYS. Surely there is a legal challenge in the works, right?
