Post-ban mini certaily OK without the arrestor or bayonet lug and probably OK with one of those if you have a thumbhole stock.
Otherwise I think you're fine with max 10-rnd mags (but they only want you to load seven).
The better news is only NYC, Long Island, and one other county I believe aren't officially fighting afgainst the SAFE Act. Police outside those areas except state police aren't even thinking of enforcing the new law -- they couldn't if they wanted to. Just don't try to sell your gun on a street corner or break some other laws with them.
