I spend way more time here reading than posting but this is just one of those topics that has my curiosity that I'd like to discuss as I can't ever find an exact answer. Hopefully with this thread we can at least temporarily put this to bed.
Over on this thread on pages 12-14 Legal AR - Tresmond Update
NYshooter1 goes on to say that
Yes there is a definition. Three new definitions were added to Penal Law Section 265, which is the definitions section, by the Safe Act:
Section 265.00 subdivision 24. "DETACHABLE MAGAZINE" means any ammunition feeding device, the function of which is to deliver one or more ammunition cartridges into the firing chamber, which can be removed from the firearm without the use of any tool, including a bullet or ammunition cartridge.
Unless I don't understand basic English, this seems quite evident that a bullet button or similar device installed would make the AR platform no longer an "assault weapon" by the smart people in charge as you need a tool making it no longer detachable by definition.
As a short term solution until this whole SAFE Act debacle is resolved, I can live with using this device to keep my AR as is.
Here is where my confusion comes in though.
According to this site Article 265 - Penal Law - Firearms and Other Dangerous Weapons which seems to be updated as recently as 5/16/13 there is no such entry for article 265.24. This implies that there is no such definition for a detachable magazine.
The reference that I was able to find for 265.24 is for bill # S01422. The full text of that bill is here Bills It looks like it was referred to codes on 1/9/13 and has never been voted on.
So with all that being said it seems to me that currently in New York there is no definition for a detachable magazing so at this point a bullet button or similar device is a no go.
