I believe a workman stole the AR lower from my basement. Farmington Hills Mi
It was still stripped and could have been taken as far back as October 23rd. to this morning Dec 16th. (my bad, but the upper shipped this week)
It was a serialized part but was made as a rifle. sold as an "other firearm"
I'll update you with the serial number when I get it.
UPDATE
Serial Number: AA4500932
