FWIW I believe that the NYS, CT, and MA laws all specifically exempt integral tubular .22-caliber rimfire magazines from the normal 5 or 10rd limits. The NY law limiting the number of rounds placed in the magazine still applies, but the magazines (and the guns they're attached to) can still be brought into MA, NYS, and CT.
