caption_attribution_description: Picture of a Colt Advanced Combat Rifle/M16A2E2 prototype taken by me at the National Museum of the American Indian.
context_page_description: The Colt ACR was Colt's entry in the U.S. DoD Advanced Combat Rifle program, which concluded with the result that none of the entrants achieved enough of an improvement over the M16 to be worth the cost.
  The Colt ACR was not a total loss, however; the scope went on to be offered by Elcan, a version of which was eventually adopted as the M145 Machine Gun Optic used on a number of firearms, especially those from Diemaco.
