U.S. Army Advanced Combat Rifle Program


Infantry Arms | The Warfighter

The U.S. Army's ACR program of the 1980s failed to find a viable successor to the storied Colt M16 rifle line.

During the 1980s, the United States Army attempted to find a replacement for its venerable Colt M16 series rifle family by adopting a design that improved upon first-hit probability by as much as 100%. A handful of entries were considered and, after hundreds of millions of dollars were spent, the program was ended with no clear winner.

There are a total of [ 4 ] U.S. Army Advanced Combat Rifle Program entries in the Military Factory. Entries are listed below in alphanumeric order (1-to-Z). Flag images indicative of country of origin and not necessarily primary operator.
