Moving from MA to NYC with firearms

For reasons that I will not get into, I am moving to the Bronx. I will say that it is related to my wife, for whom my love exceeds my absolute distain for the notion of living in New York. This is a testament to how much I love her.

What I'm looking for now is some details about moving into New York City with firearms. I have two handguns, the largest of which is a 9mm. I don't have a rifle yet, but I did buy an AR lower in Dream to Dream's recent group buy.

My understanding (though I'm not at all certain) is that I need to have a New York City carry permit merely to possess, and that there is no grace period. It sounds like I'm reasonably likely to be granted a premises-only permit (after they shake me down for $400+ in application fees) as I have a clean record, but it could take a while.

I'm not sure if I can possess the AR lower on the handgun permit, or if I will need to also apply for and be issued a rifle/shotgun permit (for an additional fee). Obviously, if I want to build the AR I would need this, but if I can get away with not having it until I decide to build, then that might be better.

What should I do in the interim while I am applying/waiting for permits to come through? It seems pretty clear that keeping them with me is not an option. I guess I'm going to have to store them with someone I trust in another state (that is legally allowed to possess them there) until such time as I can reclaim them (either by moving out of NY, or getting licensed).

I would consider moving to Westchester County instead if there is a substantially better regulatory climate, but I don't believe that's true (http://www.comm2a.org/discretionary-...ky-v-cacace-ny). If I'm mistaken, please let me know.

I've done a non-trivial amount of reading to try to answer these questions, and am eager to do more. So if you have good resources that I should consult, please post them.

In NYC the individual long guns must be registered. I haven't lived in the Bronx since 1974 but at the time I didn't even think about a handgun. I did have 2 22's both of which had to be registered and I had to be finger printed before I brought them into the city even though when I bought them in Westchester Co all I had to do is prove I was 18 back in 1968. I'm guessing that it was before the 1968 GCA was passed. To think I moved to MA after living in OH and PA.....must have been a moment of insanity.
