"Seller of ammunition" means any person, firm, partnership, corporation or company who engages in the business of purchasing, selling or keeping ammunition.
The new ammo law has basically three areas.
1. Ammo sellers must register with the NYSP superintendent. FFLs that also have a NYS firearms dealer license are exempt (but FFLs that deal in long guns only are not I believe).
2. Ammo sellers must keep a log book of ammo sales.
3. 30 days after the new database is certified operational, registered ammo sellers must receive a pass from the system before transferring ammo.
Parts 1 and 2 become active on 1/15/14, part 3 becomes active whenever the database is ready. I looked at the 2013-14 budget in S2607E and I could not find any funds for implementing Chap 1, Sec. 50, laws of 2013, so I believe the database is not funded.
Here is the bad news - the penalty for selling ammo after 1/15 is still in effect, even if the database is not operational. The ammo seller registration and record logging can still go into effect without the database. The law actually has a provision for that happening:
This requirement of this section shall not apply (i) if a background check cannot be completed because the system is not operational as determined by the superintendent of state police
