I have an 870 Police Magnum trade in from Orange County Florida Sherrif's Dept. and I'm trying to find out why my barrel has a date code of March 1994 AO but it has an address of Madison, N.C. Serial # is B-9834XXM with a Speedfeed stock and extended magazine. From what I find online the Madison plant wasn't open until about 1996 and I also thought that all Police Magnums were produced in a separate facility only at the Ilion N.Y plant. I don't think the new owners of Remington would have any info from 1994. I would appreciate any help from the forum folks. Thank you.
