I traded for this rifle last year. I've tried my best to find out it's value. I've been told that it was from the AWB in the 90's that's why it's stamped with the LEO. I've found that some new Colts come with these markings today. No help from searching the serial number through Colts site or google. Done as much homework as I can but have hit a dead end. Hopefully an AR veteran will chime in and let me know what I got exactly. Your knowledge is greatly appreciated. Thank you.
