Impressive! The absolute correct answer is that Colt bought all the plans from Armalite (actually Fairchild) and changed the meaning of the meaning of “AR” as the new owner.

The ARmalite became the Colt Automatic Rifle.

Therefore, the correct answer is dependent on what time period is being referenced.

And if you’re referencing the entire run, the correct answer is, “Both.” Which is still very annoying when it’s trivia time. :P
