Saw this photo online. However I am not sure about the provenance behind it.

The very first AR15 sales ad ever, marketed to the public as a sporting and hunting rifle. Note this was before the military adopted the full auto version, the actual assault rifle, the M16. People are trying to rewrite history and claim the inventor never intended it for civilian use.

Well, it was sold for civilian use first!

I cannot find any information that backs up the claim that this is the first Colt AR-15 Ad. The most interesting thing about this ad is the price of $189.50 and the old Colt logo.
