The U.S. Special Operations Command (USSOCOM) is replacing its M-4s with the Special Operations Combat Assault Rifle (SCAR), a modular weapon with a short-stroke piston system that eliminates carbon blow back,
which theoretically improves reliability. Some have questioned why the Army has not adopted the SCAR or another similarly designed weapon. A series of studies and tests of the M-4 and potential competitors have added to this debate, and the Army has taken steps to begin evaluating other weapons to replace the M-4.
