Sorry to hear about that. I'm sure you reported to police the serial numbers to get the guns on the national list. Thieves are often stupid. If they sell the guns to local pawn or a gun shop, often local police have a property recovery unit that requires licensed dealers to record all purchases and hold for certain amount of time and transmit serial number and seller info. At least that is the requirement in NY. If they are a little brighter and sell them privately, there is little chance of recovering your rifles especially if taken out of state. Best of luck recovering your property. M
