Hey guys, I am having a hell of a time identifying what model this AR-15 is exactly. History is it was given to my father as a gift from Colt Industries when he retired as President of their Kentucky plant in the early 1980's. I have called Colt customer service directly, but after waiting 10 min for the rep to find the serial, he asked me to call back next Tuesday because that's apparently when they have their Archival expert on staff. He said he can't find any models listed in that specific serial range.
Here's the specs:
Colt AR-15 HBAR Sporter
Caliber .223
Serial SP 2270xx
Tasco 3-9x scope
Colt cheeckpiece
Bayonet lug
20" barrel length
Closest thing I can match the specs to is this, but the "Delta" is not listed on the info punched into the frame:
