From the information I received, Remington only made a little over one thousand in a BDL, the rest of production was finished in the ADL. This was the reason for my query, coupled with a six digit serial number on this gun. I also found out that the 222 Magnum was Remington't first attempt to give the military a small, potent infantry round. Uncle Sam sent them away, told them to try again and the 223 was born.
