I've looked at and searched here, but I still have a question regarding my SP-1 AR15. The serial number on the gun is SP 1 839xx, which seems to have an extra digit. If I discount the "1" the Proof House list shows a born on date of 1978 or newer.

My question is about the "1" - it looks as if it's stamped as part of the serial number - SP 1 839xx, but I'm wondering if the actual serial number is simply 893xx. Am I reading too much into this extra digit? Is it simply part of the model designation?
