I remember a thread about a guy in New York (state), who was having trouble getting his uncle's AR-15's and pre-ban magazines released by the local cops.
But there were complicating factors there - the uncle had unregistered machineguns and large quantities of marijuana around at the time of his death.
The resolution of that situation, last I saw, was that he got all the "non-AW" guns, but they wanted receipts as proof of pre-banness on the "AW" listed guns before they'd release them to him as the heir.
Was that the one you were trying to remember, gloftoe?
