I have a colt AR15 SP1, I'm having problems verifying what year it was made. the serial number is SP 189001 everything I've found on line doesn't have 6 numbers in its serial number (series). I found a 6 number series but not even close. Can any body help?

  Probably a 1978 SP1. Look at the list at www.biggerhammer.net

  My records indicate it was made early in 1983.
