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 as the C79, a version of which was eventually adopted as the M145 Machine Gun Optic used on a number of firearms, especially those from Diemaco (now Colt Canada).
As well, a small batch of stocks during testing were cut-down to a smaller size similar to a CAR-15 buttstock. An example made its way to David Armstrong who used it as a basis for the design of the SOPMOD stock and another went to Magpul.
